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!

|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)
