This material comes from Turkmenistan and we picked it up at the Tucson show back in 2019. Haven't really seen much of it around since then, but that's not to say that it isn't out there. This material can also come from Brazil and it is stabilized. It has a natural glow and a bit of a chatoyancy to it, and if you hold it up to the light you can see the color zoning in the form of bands throughout the material.
