{"product_id":"lumenite®-facet-rough-glow-in-the-dark-strontium-aluminate-monocrystal","title":"Lumenite™ Facet Rough, Glow in the Dark Strontium Aluminate Monocrystal","description":"\u003cp\u003eThis is Lumenite™, the rarest and most precious lab gem currently available.  Each piece is individually photographed and priced.\u003c\/p\u003e\n\u003cp\u003eLumenite™ is a monocrystal of strontium aluminate, the most phosphorescent material known to science.  This material was first discovered in the late 90s and is widely used as a glow-in-the-dark pigment, but growing a large single crystal is so difficult that some scientists told us it was outright impossible.  However it turns out it is only \u003cem\u003ealmost\u003c\/em\u003e impossible, as Dr. Daniel Rytz at Brevalor devoted over a decade of his life to untangling it.  We funded the growth of a couple crystals to help advance the science and we're making it available to the community.  As an experimental and extremely difficult-to-grow material it comes at a high premium but I'm extremely glad we've had a chance to be involved--this is the most gorgeous material I've ever worked with.\u003c\/p\u003e\n\u003cp\u003eNote that the crystals are still not completely perfect, showing a silky chatoyance caused by twinning, but their clarity is still good and they cut absolutely stunning gemstones.\u003cspan\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eThe hardness is around 6.5, so it is not ideal for ring wear but great for pendants and earrings.  It cuts and polishes well with diamond.\u003c\/p\u003e","brand":"Turtle's Hoard","offers":[{"title":"Edge, 10.1×8.8×7.3mm,
