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","url":"https:\/\/store.gemsofscience.com\/products\/gagg-pixels-yellow-lumogarnet","provider":"Gems Of Science","version":"1.0","type":"link"}
