{"product_id":"ghost-garnet-aka-pr-luag-lumogarnet-facet-rough-green-with-orange-glow","title":"Ghost Garnet aka Pr:LuAG Lumogarnet Facet Rough Green with Orange Glow","description":"\u003cp\u003eThese are lab-created LuAG (Lutetium Aluminum Garnet) facet rough.  Each is labelled with its gram weight and letter in the photo and they can be purchased individually.\u003c\/p\u003e\n\u003cp\u003eLuAG is an exotic lab-created crystal with the same structure as natural garnets, but a composition and properties which are impossible in nature.  While the most famous type is the neon green cerium-doped LuAG, when doped with praseodymium instead you get this very odd multifluorescence: longwave UV gives a pale green, shortwave gives violet and best of all blue light gives a strong orange glow.  This means that against a black background in blue-leaning lighting you have a light green stone with a visible orange glow--very uncanny!\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003ePr:LuAG, like its more famous brother Ce:LuAG, is used as a scintillator in high end applications.\u003c\/p\u003e\n\u003cp\u003eLuAG facets similarly to YAG (Yttrium Aluminum Garnet) - ie: pretty much perfectly and easily without much complaint. It has a hardness of 8.5 and no durability issues. It has very good optical properties with an RI of 1.83, just slightly better than yag.\u003c\/p\u003e","brand":"Turtle's Hoard","offers":[{"title":"1pc under 1g (crumb)","offer_id":50704370139424,"sku":"Rough_Ghost_Crumb","price":10.0,"currency_code":"USD","in_stock":false},{"title":"1pc 1-2g","offer_id":50704370172192,"sku":"Rough_Ghost_1g","price":36.0,"currency_code":"USD","in_stock":false},{"title":"1pc 2-3g","offer_id":50704370204960,"sku":"Rough_Ghost_2g","price":48.0,"currency_code":"USD","in_stock":false},{"title":"1pc 3-4g","offer_id":50704370237728,"sku":"Rough_Ghost_3g","price":64.0,"currency_code":"USD","in_stock":false},{"title":"1pc 4-5g","offer_id":50704370270496,"sku":"Rough_Ghost_4g","price":80.0,"currency_code":"USD","in_stock":false},{"title":"1pc 5-6g","offer_id":50704370303264,"sku":"Rough_Ghost_5g","price":96.0,"currency_code":"USD","in_stock":false},{"title":"1pc 6-7g","offer_id":50704370336032,"sku":"Rough_Ghost_6g","price":112.0,"currency_code":"USD","in_stock":true},{"title":"1pc 7-8g","offer_id":50704370368800,"sku":"Rough_Ghost_7g","price":128.0,"currency_code":"USD","in_stock":true},{"title":"1pc 8-9g","offer_id":50704370401568,"sku":"Rough_Ghost_8g","price":144.0,"currency_code":"USD","in_stock":true},{"title":"1pc 9-10g","offer_id":50704370434336,"sku":"Rough_Ghost_9g","price":160.0,"currency_code":"USD","in_stock":true},{"title":"1pc 10-11g","offer_id":50704370467104,"sku":"Rough_Ghost_10g","price":176.0,"currency_code":"USD","in_stock":true},{"title":"1pc 11-12g","offer_id":50704370499872,"sku":"Rough_Ghost_11g","price":192.0,"currency_code":"USD","in_stock":false},{"title":"1pc 12-13g","offer_id":50704370532640,"sku":"Rough_Ghost_12g","price":208.0,"currency_code":"USD","in_stock":false},{"title":"1pc 13-14g","offer_id":50704370565408,"sku":"Rough_Ghost_13g","price":224.0,"currency_code":"USD","in_stock":false},{"title":"1pc 12.3g","offer_id":50704377348384,"sku":"Rough_Ghost_001","price":172.0,"currency_code":"USD","in_stock":false},{"title":"1pc 12.59g","offer_id":50704377381152,"sku":"Rough_Ghost_002","price":176.0,"currency_code":"USD","in_stock":false},{"title":"1pc 13.5g","offer_id":50704377413920,"sku":"Rough_Ghost_003","price":189.0,"currency_code":"USD","in_stock":true},{"title":"1pc 14.8g","offer_id":50704377446688,"sku":"Rough_Ghost_004","price":207.0,"currency_code":"USD","in_stock":true},{"title":"1pc 16.0g","offer_id":50704377479456,"sku":"Rough_Ghost_005","price":224.0,"currency_code":"USD","in_stock":true},{"title":"1pc 16.1g","offer_id":50704377512224,"sku":"Rough_Ghost_006","price":225.0,"currency_code":"USD","in_stock":true},{"title":"1pc 16.5g","offer_id":50704377544992,"sku":"Rough_Ghost_007","price":231.0,"currency_code":"USD","in_stock":false},{"title":"1pc 22.7g","offer_id":50704377577760,"sku":"Rough_Ghost_008","price":317.0,"currency_code":"USD","in_stock":false},{"title":"1pc 24.7g","offer_id":50704377610528,"sku":"Rough_Ghost_009","price":345.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0753\/6794\/0384\/files\/IMG_0217copy.jpg?v=1757972523","url":"https:\/\/store.gemsofscience.com\/products\/ghost-garnet-aka-pr-luag-lumogarnet-facet-rough-green-with-orange-glow","provider":"Gems Of Science","version":"1.0","type":"link"}
