It is what we call a 'lumogarnet' - a synthetic garnet with incredible fluorescence. It glows a bright yellow, slightly greener and brighter than already-bright Ce:YAG. This material is like an upgraded version of the classic GGG crossed with an aluminum garnet (like YAG and LuAG) to give it excellent hardness (8) while maintaining a high RI (1.9) and generally excellent gem properties. \u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eThis material also glows in the dark, though the amount varies from piece to piece.  They try hard to make sure it won't have any afterglow but mistakes do get made sometimes and these gems are the ones that didn't make the cut for whatever reason.\u003c\/p\u003e","brand":"Turtle's Hoard","offers":[{"title":"Smaller Complete GAGG Pixel (20x4.3mm avg 12ct)","offer_id":46001346642208,"sku":"Pixel_GAGG_Small","price":50.0,"currency_code":"USD","in_stock":true},{"title":"Larger Complete GAGG Pixel (27x5x3mm avg 14.5ct)","offer_id":48563359482144,"sku":"Pixel_GAGG_Whole","price":50.0,"currency_code":"USD","in_stock":true},{"title":"Faceted Larger GAGG Pixel (approx 27mm x 5 mm, avg 7.4ct)","offer_id":46002284331296,"sku":"Pixel_GAGG_Faceted","price":150.0,"currency_code":"USD","in_stock":true},{"title":"Faceted GAGG Pixel with inclusions (19-20mm long avg 6ct)","offer_id":46002284364064,"sku":"Faceted_GAGG_Pixel","price":90.0,"currency_code":"USD","in_stock":false},{"title":"Damaged Larger GAGG Pixel (has cracks and or chips)","offer_id":48563359514912,"sku":"Pixel_GAGG_Damaged","price":35.0,"currency_code":"USD","in_stock":false},{"title":"Incomplete Larger GAGG Pixel (fragment of a complete pixel)","offer_id":48563359547680,"sku":"Pixel_GAGG_Fragment","price":25.0,"currency_code":"USD","in_stock":false},{"title":"Damaged Smaller Complete GAGG Pixel","offer_id":49984311001376,"sku":"Pixel_GAGG_Small_Chipped","price":30.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0753\/6794\/0384\/files\/IMG_0049_2e1a66f9-b051-461e-a8dd-8c9763d9998f.jpg?v=1716495745"},{"product_id":"lyso-pixels-raw-and-faceted-loose-gems-blue-fluorescent-scintillator","title":"LYSO Pixels Raw and Faceted Loose Gems Blue Fluorescent Scintillator","description":"\u003cp\u003eThese are loose scintillator pixels of LYSO (Lutetium Yttrium Oxyorthosilicate) which were made for PET scanners but didn't end up meeting the cut.  Some are full prisms measuring 20x4x4mm, some are partial (either broken pixels or pixels that caught the edge of the crystal and show some of the rounded crystal face).  We have also had some faceted as long pixel gems which are very bright and beautiful!\u003cbr\u003e\u003cbr\u003eLYSO is a very unusual crystal grown for use in science and industry.  It has a clear base and very strong blue fluorescence. It glows incredibly bright under UV light as well as higher energy radiation, and because of this it can be used to detect invisible gamma rays, xrays and even alpha rays. This type of LYSO has been optimized for ultra strong fluorescence with no afterglow (it does not glow in the dark, only with UV exposure). Its fluorescence is so strong it has a striking blue glow in sunlight--this effectively gives it a color change effect, since it looks colorless under room lighting and light purple-blue outdoors. It has a very interesting and unique look which you can't find anywhere else.  Note that LYSO reacts much more strongly to 365 nm UV, and 395nm will be much less effective.\u003cbr\u003e\u003cbr\u003eAsianometry on youtube recently made a cool video about this material which you can watch here https:\/\/www.youtube.com\/watch?v=XpYYGiUX0x0\u003cbr\u003e\u003cbr\u003eLYSO is not very hard at around 5.8, just under tanzanite, and as such is not a good choice for a ring, though it would be great in a pendant or earrings.\u003c\/p\u003e","brand":"Turtle's Hoard","offers":[{"title":"Full LYSO Pixel Prism (avg. 11ct)","offer_id":47380883407136,"sku":"Pixel_Lyso_Whole","price":67.0,"currency_code":"USD","in_stock":true},{"title":"Partial LYSO Pixel Prism (avg. 5ct)","offer_id":47380883439904,"sku":"Pixel_Lyso_Partial","price":32.0,"currency_code":"USD","in_stock":true},{"title":"Lyso Pixel Prism Shreds (Set of 2-3 flat shards)","offer_id":49669555159328,"sku":"Pixel_Lyso_Shreds","price":15.0,"currency_code":"USD","in_stock":false},{"title":"Faceted LYSO pixel (avg. 5.5ct)","offer_id":47380883472672,"sku":"Pixel_Lyso_Faceted","price":196.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0753\/6794\/0384\/files\/lysopixels.jpg?v=1704307993"},{"product_id":"retro-pixel-retrohex-cut-green-laser-garnet-10ct","title":"Retro Pixel RetroHex Cut Green Laser Garnet 10ct","description":"\u003cp\u003eThis is a special \u003cspan\u003eRetroHex\u003c\/span\u003e pixel cut I designed and am testing out.  It is cut in vivid green laser garnet (Vanadium YAG)  The stone weighs in at a 10 carats and measures  25.1x19.5mm\u003c\/p\u003e\n\u003cp\u003eI'm a pixel artist and I love retro games (or as we called them when I was a kid, games), so one of my favorite things to cut are rupees.  I have tried hybrid pixel-rupee cuts before but doing a classic pixel cut really doesn't let you do a proper rupee crown, so I decided to try a totally different approach which I really like.\u003c\/p\u003e","brand":"Turtle's Hoard","offers":[{"title":"Default Title","offer_id":48976681173280,"sku":"TH_CustomCut","price":420.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0753\/6794\/0384\/files\/IMG_0010_72f6dfaa-6e95-4dc8-8bdd-9d56b00ae657.jpg?v=1721277790"}],"url":"https:\/\/store.gemsofscience.com\/collections\/pixels.oembed","provider":"Gems Of Science","version":"1.0","type":"link"}
