What Is Angel Aura Opalite? Is It a Gemstone?

I stumbled across pictures of "Angel Aura Opalite" this morning, and the colors really caught my eye---I honestly gasped at how beautiful it is!  But what is it exactly?  Is it a gemstone?  What is "Angel Aura"?

What is Opalite?
It's not a gemstone or a mineral---it is a type of opalescent glass.  Opalite is always man-made glass.  It is NOT quartz.  

Mystic Coatings
There are different metals, such as gold, silver, platinum, and/or titanium, that are used to coat gemstones, rhinestones, crystals, or CZ, that cause beautiful rainbows of colors.  These look like a soap bubble, or oil on water---a rainbow of blues, greens, teals, many different and always-changing colors. 

Angel Aura Quartz
Angel Aura is a coating that's very popular.  Through a special vapor deposition process, genuine silver and platinum vapor is fused to heated quartz (or other stone) in a vacuum chamber.  This allows the gold atoms to fuse with the outside crystals.   Sometimes this same coating is called "Starlight" on CZ jewelry, for example.
Rainbow Aura Quartz

This same process using other vaporized metals on quartz or glass or on other minerals results in  "Rainbow Aura" (titanium and gold) or golden "Sunset Aura" or  "Flame Aura" (electrostatic-bonded titanium onto unheated quartz) or  "Opal Aura" but the process is the same---vaporized metals are permanently bonded to crystals, often quartz crystals, but sometimes on other gems such as topaz, or CZ or crystals (such as Swarovski crystals).  Although this process is usually permanent, sometimes the coating can get scratched so it's best to be careful when wearing mystic coated jewelry.
Aqua Aura Quartz

When gold is fused to quartz, it's called "Aqua Aura" and leaves a beautiful blue-rainbow coating.

Sadly, there are even fake "aura quartz" stones---these are perhaps just painted or cheaply coated (and it scratches right off), or sometimes "quartz clusters" are just pieces glued together, so beware when buying online.


These "mystic" coated crystals or gemstones have been around for a long time.  The results are extremely beautiful in a wide range of colors.  Mystic coated quartz is very popular, including mystic coated Amethyst, as well as Mystic Topaz.

Angel Aura Opalite is a coated glass, not a gemstone--but is incredibly beautiful and fascinating to look at!

Is "Monalisa Stone" a Gemstone? Answer: No

Someone asked me about a new stone called "Monalisa" stone, and I've never heard of it until today.  Just googling that reveals that it is a manufactured GLASS stone in India, and sold as a glass stone from 

It is NOT a gemstone.

Here is Indiamart's array of colors available for this glass stone:

Offered as "treated gemstone"--NOT!

It's a pretty "cat's eye" effect glass stone that is seen in a lot of costume jewelry.  I've seen it many times but never knew it was called "Monalisa stone" until today.  These glass beads are made with horizontal filaments inside that give it that distinctive "cat's eye" effect.  Please note that there are genuine gemstones that display this cat's eye effect---everything from rubies to quartz.  But these aren't gemstones---these Monalisa stones are manufactured glass, and is clearly stated as glass.  Here's a link to indiamart's website---they are honestly selling these glass "badam" stones (Hindi for "almond"---their shape) and are not trying to sell them as mineral gems. 

Google reveals that this new term, Monalisa Stone, is found pretty much exclusively on Etsy.  Etsy jewelry designers seem to offer these "new gems" probably because the gemstone wholesalers in India heavily market their stones to Etsy sellers who really don't investigate what something is (such as silverite).  But a simple google search, which took me a minute, shows right away that this is GLASS, not a gemstone!

However, there are some sellers who are offering this glass as a "gemstone" which is wrong.  It is not a gemstone, it is a glass stone.
Just glass with embedded filaments
Pretty--not a gemstone though

I'm not begrudging anyone for selling jewelry or trying to "call out" anyone, but as an example, there is a seller who has this Monalisa Stone set in a sterling bangle and although it's very pretty (in various colors and shapes), it's NOT a gemstone and nowhere do they say that this is glass.  They say or imply that it's a natural gemstone like their other jewelry---and that's really not right. 

There are many pieces of jewelry on Etsy with this Monalisa stone, and some sellers say it's glass, some don't say what it is, and some outright claim this is a gemstone.  It's NOT a gemstone---it's definitely glass. 

It's pretty---but buyer beware: it's glass, not a mineral. (Have I said that enough? LOL)
You can see the post through the glass, and fracture features of glass on the side.

Is Any "Hydroquartz" Genuine Synthetic Quartz? What is a Nanogem?

Per the GIA (Gemological Institute of America):

Is there synthetic citrine?

Quartz is grown in laboratories for industrial purposes and to make synthetic amethyst. Some of the material becomes synthetic citrine quartz.

The key word here is "synthetic."  Synthetic gemstones are lab-created gems that have the same chemical and physical properties as natural gems, plus of course the same optical properties. In other words, they look the same but also are chemically identical.


There is a difference between "synthetic" and "hydroquartz" stones. Although I've written many times about all of the so-called "Hydroquartz" in many different colors, such as London Blue Quartz, Swiss Blue Quartz, Ruby Quartz, Emerald Quartz, Tanzanite Quartz, and so forth, I will mention again: these are not genuine Quartz at all, but are glass.  This material is sold in blocks and used to be called "Hydroquartz Glass" but the word "glass" has gone missing in recent years.  Also quartz and glass are similar looking ("optical" quality), quartz is a mineral with crystal structures and glass has none (so different physical and chemical properties).

Synthetic, or created, Emerald
Lab-created gemstones are an expensive process.  It's cost-effective to create precious gemstones such as corundum (rubies and sapphires) and other gems.  Amethyst, a semi-precious gem, is the most popular and expensive of the quartz gems. Amethyst, which is purple quartz, is grown in labs because it is the most valuable type of quartz.  In fact, as I've mentioned, it's getting a little more difficult to find natural Amethyst because there is SO much of the synthetic variety---which can range from light pinkish purple to deep purple.  There is no difference, chemically or physically, between synthetic and natural Amethyst.

Golden Citrine--Natural, Heated
Citrine is heated Amethyst.  It can be golden, yellow, or a deeper "fire citrine" orange color. It can occur naturally, but virtually all of the Citrine in jewelry is treated (heated) Amethyst.  Amethyst and Citrine have the same chemical/physical properties, but are different colors. There is no way for a gemologist to tell the difference between "natural" Citrine and heated Amethyst.

Reputable jewelers and wholesalers will identify lab-created stones as "synthetic" including Rio Grande Jewelry.  They offer synthetic gems---emeralds, rubies, sapphires, and Moissanite---but all of their Amethyst offered right now on their site is natural. I don't recall ever seeing synthetic Amethyst there, but I may have missed it. They clearly identify each gem sold as "Natural" or "Synthetic" as well as any treatments.  Their natural Citrine is clearly identified as "Heat-treated".  Rio Grande Jewelry is the most reputable wholesale company that serves the jewelry industry worldwide.  They do NOT offer any kind of "hydroquartz" of course.
If Amethyst is lab-grown, then it would make sense that Citrine and probably Ametrine are also produced as well. 

However, while synthetic Citrine exists, and described as "synthetic," not ALL Citrine "hydroquartz" is genuine quartz though.  There are also lots of glass stones sold as various colors of "Ametrine" including weird colors such as blues, greens, and bright pink in addition to purple and yellow---obviously NOT Ametrine!

Synthetic gemstones, including lab-created Amethyst and Citrine, would therefore be sold at a higher price than other "hydroquartz" stones, which are inexpensive and sold online.  Please keep in mind that a lot of Citrine "hydroquartz" stones being sold online are not actual quartz--not really synthetic gemstones--but are still just colored glass.  They are non-crystalline.


A Nanogem is a man-made, glass-ceramic material with nano-sized crystals of spinel within its matrix. These stones have exceptional physical and optical properties with a more uniform color than CZs, synthetic quartz or synthetic corundum, and a hardness, reflective index and luster that is very close to natural gemstones. 
Purple Nanogems--Not Amethysts!
Rio Grande has  these stones in rings on their website, in colors that look like Amethyst ("purple Nanogems"), and other pieces that are pave-set with these stones in a wide variety of colors.
They offer these Nanogems in a limited variety of styles and colors as they are "new" to the marketplace.

It's impossible to tell online whether Amethyst or Citrine are actually quartz or are glass.  It would have to be examined by a gemologist for crystal structure.

So therefore, it should NOT be assumed that "Amethyst hydroquartz" or "Citrine hydroquartz" are genuine gems.  Lab-grown gems, including Amethyst and Citrine, are referred to as "synthetic" gems.  Personally, I would prefer purchasing "Synthetic Amethyst" (as opposed to anything described as "hydroquartz), and then have it verified.  Since every single piece of hydroquartz that I have purchased and have had examined by a certified gemologist has turned out to be non-crystalline glass,  I do NOT recommend "hydroquartz."

Describing Gems in Millimeters: Some Comparisons to Help

When buying gems or jewelry online, it's hard to know what "8mm" means in terms of size.  You can look at a ruler and on the opposite edge of Inches are CM (centimeters) and MM (millimeters).  Inches have lines for each 1/8 of an inch and 1/16 of an inch.  On the centimeter side, there are 10mm to one cm, and about 25mm to one inch.  But that's still hard to judge the size of a gemstone. Chain widths are also measured in millimeters, so it can be surprising to see how tiny a chain will look in person. Chains can be as small as under 1mm (.8 or even smaller).  Nylon or silk cords can be less than .5mm---like a thread.

Rulers have inches on one edge, mm on the other

Sellers take very close pictures of the jewelry they're selling and buyers can be disappointed at how tiny gems actually are, even with measurements listed.
1-ct diamond ring = 6.5mm diameter

So I put together a quick chart to help judge sizes, comparing millimeters to everyday objects and the approximate carats of round-cut diamonds:

                         SIZE              DIAMETER
      • 1mm          Grain of sugar      
      • 1.25mm     1-point round diamond
      • 4mm          .25-ct. diamond, match head
      • 5mm          Pea, and .50-ct. diamond
      • 6mm          Pencil eraser 
      • 6.5mm       1-carat round diamond
      • 8mm          2-carat round diamond 
      • 9.25mm     3-carat round diamond
      • 10mm        Standard thumbtack head
      • 11mm        AAA battery, and 5-ct. diamond
      • 14mm        AA battery
      • 16mm        Button on a pair of jeans
      • 17mm        A battery
      • 18mm        Dime
      • 19mm        Penny
      • 21mm        Nickel
      • 24mm        Quarter 

      •  3mm  = 1/8"
      •  6mm  = 1/4"
      •  8mm  = 5/16"
      • 10mm = 3/8"
      • 13mm = 1/2"
      • 19mm = 3/4"
      • 23mm = 7/8"
      • 20mm = 1"
 I hope this helps you "see" the sizes of gemstones so you know exactly what you're buying!

Do Gemstones Break? Can a Diamond Break? Info About Gem Hardness

If you hit a diamond with a hammer, it’ll shatter into a dozen pieces. If you hit a piece of quartz with a hammer, it’ll split in two. If you hit a piece of jade with a hammer, it’ll ring like a bell!

That's an old jeweler's saying.   We all know that diamonds are the hardest gemstones.  So can a genuine diamond really shatter?  What if it's dropped onto the floor?  What about other gemstones?

I read in the Amazon forums that a buyer felt that their gemstone necklace was "fake" because the stone broke when she dropped it onto her tile floor!   She felt that only something that was glass would break from dropping it onto a hard floor.  She expected a refund, and the jewelry seller sought advice from other Amazon sellers, most of whom aren't jewelers.  Some of the responses were in favor of the buyer (they "didn't know if genuine gems would ever break"), and others in favor of the seller.  So I thought I'd write about gemstones, their hardness, and their wearability.


The "hardness" of a gem is only one factor in determining a gemstone's durability.  Gemologists take into consideration other factors:  ability to withstand heat, light, chemical exposure (household cleaners etc.), and humidity, stone treatments, gem cleavage, and even the cut of a gem.  So gemstones are evaluated by (1) hardness; (2) toughness; and (3) stability. All of these factors should be weighed when deciding which gemstone is right for you.


This is a really misunderstood and confusing term.  In gemology, the word "hardness" has a different meaning---it simply means the ability to resist scratches and abrasions, and nothing more!  So really the hardness of a gem is measured by its "scratchability".

In the early 1900s, Freidrich Mohs developed a scale from 1-10 to describe minerals' ability to be scratched, with 1 being the softest and 10 the hardest.  This is known as the Mohs Scale of Hardness.  All gems are rated between 1-10 but the Mohs scale uses the following gems as an example:

Quartz Geode
Glass is about 5.5 on the Mohs scale so anything harder can scratch glass (not just a diamond!) including a CZ or quartz.  Only a diamond can scratch itself and all other gemstones.  The most important number on this scale is 7--quartz.  Why? Because quartz is the most common mineral on earth, and tiny flecks of quartz are constantly airborne (all the little specks of "dust" in the air are mostly quartz particles!) and so any gem with a lower Mohs grade than 7 will be easily scratched just by dust!   This is why it's advisable to rinse your jewelry off under water before rubbing it with a cloth--to avoid scratching it.

Each one of these minerals can scratch the one below it, and can be scratched by the one above it.    And the scale isn't linear, but is relative----Corundum (9) is twice as hard as topaz (8), and diamond (10) is four times as hard as corundum.  And with the mineral Kyanite, the hardness can vary within one crystal from 4 to 7.5!

There are also many minerals that are rated halfway between numbers, such as tourmaline which can range from 7.0 to 7.5.


This is the ability of a gem to resist breaking and chipping. 

Nephrite Jade--VERY Tough!
There is a Gemstone Fracture Toughness  Scale that measures the work required to separate a gemstone along a cleavage plane.   Values run from 600 (corundum) to 225,000 for nephrite jade.  Diamonds are rated at about 5,000-8,000.   A diamond is the hardest gemstone on the Mohs scale, but is also brittle.  The steel of a hammer won't scratch the diamond, but hitting it with the hammer will shatter it.  Daily wear of a diamond, with all the things the diamond will rub against and clunk against, over time will scratch the stone.  "Wearability" (also referred to as "toughness" or "durability") is the degree in which a gem will show wear.   Gems with a hardness of 6 (such as Opal) will quickly loose their polish due to tiny scratches over time.

Gems softer than Quartz (7) will lose their polish just from simply cleaning it over time.  Gems with a Mohs rating of 7 and up are considered very wearable a suitable for everyday wear.  Wearability is graded as Excellent, Very Good, Good, and Poor. Opals have a "Poor" wearability rating, which means it should be saved for special occasions or set in protective settings.
Opals--3% to 21% Water!

So.....a gemstone's "durability" is a function of its resistance to scratches (hardness) + resistance to breakage (toughness) + other special properties such as cleavage planes (or in the case of jade that "rings like a bell" mentioned at the top---an interlocking structure that makes it very tough.)   Certain gemstone cuts, like marquise, are more prone to chipping, as are gems that are loose in their settings.


Just because a gem is hard doesn't always mean its wearability is "excellent."  Some gems are sensitive to chemicals, temperature changes, or even sweat!

Diamond cracked by thermal shock
Diamonds are very stable, but can also break when exposed to extreme temperature changes. "Thermal shock" is the term that describes the damage that can occur from extreme temp changes.

Some gems are vulnerable to humidity changes.  Opals can lose their moisture in dry conditions and crack.  Some gems can absorb water---malachite, amber and azurite.

Citrine, Amethyst, Prasiolite
Some gemstones can change or lose their color when exposed to light---amethyst, citrine, prasiolite, kunzite and topaz can fade when exposed to prolonged sunlight.  Organic gems can be ruined if exposed to prolonged light and heat---amber, coral, pearls, jet, and ivory.  Enamel can also be ruined when exposed to heat.

Chlorine and perfumes and makeup are chemicals that can also damage or discolor some gems, such as pearls.  Chlorine can also damage gold mountings!   Ammonia will damage the shine on turquoise, malachite, and coral.  Turquoise can easily absorb all sorts of oils and chemicals.


Fracture-Filled Emerald
Some gems are coated. Some are facture-filled which can be damaged from heat and exposure to heat or solvents, like alcohol, or damaged from ultrasonic cleaning.


Gemstone hardness alone isn't a measure of a gem's toughness or wearability.  There are many other factors to determine how well a particular gem will wear over time.

So regarding that woman's assertion that "only a fake gem would break"--- she is WRONG.  Any gemstone can break when dropped onto a hard surface like a tile floor, including a diamond.   Some manmade stones, such as the Cubic Zirconia with a Mohs hardness of 8 or 8.5 or Moissanite with a Mohs hardness of 9.25, will resist scratches and chips better than most other gemstones.

Most gemologists or great websites such as the GIA will list each gemstone's Mohs rating, plus wearability grades.

It's important to always treat your gemstone jewelry with care---don't drop it, bump it, or wear while swimming or doing housework or working around chemicals.  Keep jewelry clean and safe while not wearing it.  Keep your jewelry in a jewelry box, away from other pieces of jewelry so they don't bump each other. Make sure any prongs are secure and stones aren't loose.  This will ensure that your fine jewelry will remain beautiful and last for generations.

"Opalite" Opal Simulant, Kyocera "Opals"---Not Really Opals

Someone read my blog post about the glass "opalite" that I've written about HERE.   They commented about a synthetic (created) Opal that is sold as opalite, and how it wasn't glass.  I responded, but I thought I'd write a little about it here also.

Back in the 1970s or early '80s, a Japanese company was manufacturing a plastic simulated opal and called it "opalite".  They had claimed it was a cultured opal, or lab-grown opal.  In the jewelry world, the word "synthetic" doesn't mean "fake"---it means a gemstone that is cultured that has the SAME chemical, physical and optical properties as its natural counterpart.  This would mean that a synthetic gemstone (such as synthetic ruby or sapphire, for example) is IDENTICAL to a mined gem, but would be flawless.

Plastic Opalite from GIA (1989)
In the 1980s, the GIA (Gemological Institute of America) did some tests on this "opalite" Opal product.  It was found to be PLASTIC, not an opal, and was identical to a lot of other simulated opal products found. 

Per the GIA: 
"A plastic imitation opal that shows true play-of-color was advertised as "new" and offered for sale under the trade name "Opalite" at the Gem and Lapidary Dealers Association (GLDA) Tucson show in February 1988. Subsequent gemological testing proved that this material was virtually identical to the plastic imitation opal previously described in the literature that was known to be manufactured in Japan. It is now being marketed worldwide under a new name"

HERE is a link to the pdf file from 1989 that is interesting to read, and has all the findings.

Tested by GIA--NOT synthetic
Now, a Japanese company is manufacturing a Kyocera "opal" that is also NOT a true synthetic opal.  It is manufactured in blocks. It does NOT have the same chemical and physical properties of a genuine Opal and is therefore not a synthetic or cultured opal----it is a simulated opal.  A "simulated" gem (in this case Opal) is just something that is made to LOOK LIKE a gemstone---it's not a synthetic, which is grown and IS a gem, although manmade. 
Blocks of *simulated* opal --- not genuine Opal

HERE is a very interesting article from the GIA regarding Kyocera opals---no longer marketed as "opalite" by the way.  The conclusion in those findings is that the Kyocera opals are just simulants, not synthetics.  In other words, they are NOT opals.

While looking at images of Kyocera simulated opals, I found that there is a jewelry designer that is selling this simulated opal as "Kyocera opal" set in base metals (plated brass) for premium prices.  Buyer beware---a higher price tag gives the illusion of quality (basic Marketing 101) but doesn't mean it's genuine.    Here are some examples of the colors of SIMULATED (not real!) opals used:

None of these are opals---all are Kyocera SIMULATED Opals
This is considered "fashion jewelry" or "costume jewelry", not fine jewelry which incorporates genuine gems set in precious metals (gold, silver, plastinum). 


Opalite Glass--NOT a gem
In the early 1990s or around the time that this particular "opalite" opal was tested and confirmed to be just plastic, manufacturers in Hong Kong began making an iridescent glass that was known as "opalite glass".  Sellers seem to have forgotten the word "glass" in describing this material now, which is why I've written about it several times.  Current "Opalite" products sold are IRIDESCENT GLASS, and nothing more. 

Opalite has an iridescent glow that changes color when held against a dark or a light background.  It's more blue against darker colors, and more golden or pink against light colors.
Opalite--note the color changes

Another blogger concludes that this isn't even glass, but is plastic with cellophane inside!  Perhaps that's true, and some are plastic, but the ones I've seen in person have been glass.  Either way---NOT a gem!

The same designer I mentioned above who sells simulated Kyocera opals, is also selling Opalite.  Here's a great example of how colorless this glass (plastic?) is against a light background:

Opalite (glass) earrings---not gems

Opalite IS Simply Glass (Not a Gemstone) and is NOT "Opal Glass," and Comments I Receive via Blogger

Opalite Glass
Today I've heard a couple of times (via the blogger "contact" form) from someone responding to my "Opalite is Just Glass and Not a Gemstone" post, who insists that Opalite "isn't just glass" because it's made with minerals which give it a glow.  I'm not going to publish the comments and I can't respond to their email (since their settings are set to "" as their email, it goes back to me!), so I'm going to respond right here in this separate post.  Hopefully this is a little bit informative for this person, and for anyone who might read this and wonder, "If glass is made from minerals, why isn't it a gemstone?"  But basically, this person today has confused Opalite (which is a man-made glass made in China for the jewelry industry as a simulated Opal or Moonstone) with "Opal Glass" which is a "thermally opalizable glass" used in manufacturing (jars, etc.) and who referred me to this patent from 1970.
This patent information is about Opal Glass---used in things like Corningware and cosmetics jars.  This has NOTHING to do with Opalite, used in jewelry.  I can see how this could be confusing, especially when unscrupulous sellers try to hawk this opalite glass as "opal glass" or "opal moonstone" and other misnomers.  I assume this person googled "opal glass" and found their way to my blog as well as that patent info.  So since this is confusing for some people, here is a little more VERY basic info about glass in general, and Opal Glass in particular: 

Ancient Roman Glass--Clear when Made

Glass (man-made) is made from melting minerals together at a very high temperature.  These minerals are silica (silicon dioxide), limestone (calcium carbonate), and soda ash (sodium carbonate), melted at 1700 degrees C. Glass is amorphic---meaning it has no crystalline structure.  The chemical structure of glass is SiO2  There are many other types of glass such as "crystal" or leaded glass (which adds lead oxide),  borosilicate glass which is made with boron trioxide which makes it very sturdy and is used as test tubes and sold as Pyrex for baking, for example, "Vaseline glass", plus many other types of art glass and so forth.

There are 3 different ways to make colored glass. Adding different minerals/metal salts to the basic glass recipe results in colors of glass.  Iron or Chromium is added for green glass; Cobalt for blue glass; Gold, Copper and Tin may be added to make red glass; and so forth.  HERE is a great website that explains this in detail along with a great chart at the top of the page.  Some glass is colored by suspended particles (colloidal) of minerals in the glass.  "Goldstone" and "Blue Goldstone" are great examples of glass with suspended minerals.

Vintage "Opal" or Milk Glass Steins

This is a type of art glass made in the 19th Century and was known as "Opal Glass", then later called "Milk Glass".  It is a milky white opaque to translucent glass, but can also be found in assorted colors, formed in vases and cups and decorative objects.  It was made with different recipes---sometimes using a little arsenic, sometimes tin oxide, and usually fluorite.  This means that this glass will become fluorescent under a black light.  It's a collectible vintage glass now.

There is a patented method of making "opal glass" from 1972 that describes how "opalescent glass" is manufactured for "thermally opalizable glass".  This is glass used in oven ware (low expansion, heat-resistant).  As it says in the patent info, opal glasses are "widely used in the fields of science, industry and commerce in the form of containers for...cosmetic creams, deodorant containers, lighting globes..." etc. The patent goes on to describe the chemistry of this oven-safe glass.

This has absolutely NOTHING to do with Opalite--a glass made in China specifically for the jewelry industry.
 Knowledge of basic science will tell you that everything that is not growing or living (such as plants, animals) is a mineral, or made from minerals. "If it can't be grown, it must be mined."  Even living things (including people) are made of minerals.

The most-read post in my blog has been regarding Opalite glass.  This is a man-made glass and is often sold to consumers as a gemstone, with sellers calling it "Sea Opal" and "Opal Moonstone" and even just "Moonstone" when in fact it is NOT a gem, but is simply glass!  Glass which has no crystal structure, despite being made from minerals, is simply GLASS and therefore not a gemstone.  "Fused Glass" is often sold as Quartz when in fact it is also just glass (which I've written about several times as well).  I wrote about Opalite glass more than once, and have posted pictures of Opalite glass and Moonstones and Rainbow Moonstones, and have answered literally hundreds of questions about this Opalite-as-gemstone scam.  And it IS a scam when someone claims it is a "gemstone"!  I get a lot of questions asking if something is a real gemstone (and I enjoy getting questions and always try to help).  Sometimes I'll hear from someone who is trying to correct me on something---that's great!  I've updated many of my posts when I get solid information to add.  I'm here to learn too!

Anyway, whoever "Me" is who wrote to me regarding this patent and argued that "opalite" isn't "just" glass because it's made with minerals----thank you for taking the time to send me emails.  I hope you find this information helpful and informative. If  you have further questions regarding glass in general or Opalite glass in particular, please provide your email address so I can respond.
