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":"bgo12-bismuth-germanate-facet-rough","title":"BGO12 Bismuth Germanate Facet Rough","description":"\u003cp\u003eThese are BGO-12 aka Bismuth Germanate facet rough.\u003c\/p\u003e\n\u003cp\u003eThis is a real cool rarity in the gem world.

scintillator crystals, recognized for its inherent fluoresence to high energy radiation and useful for detecting X-rays and gamma rays.  Unfortunately its fluorescence is rather weak and requires high
