Faceted Yb:YAG Gemstones, Light Blue Fantasy Cut Laser Garnets yap This Europium-doped fluorite is grown

This Europium-doped fluorite is grown for science - these crystals are valuable because they are extremely sensitive to many kinds of radiation (not just UV)

ﺁ  sourced from an old collectionﺁ  The color intensity and darkness varies considerably from stone to stone

only when looking close with direct point lighting

It's the hardest gem that can feasibly be cut into a die and it is more brilliant than a diamond

Faceted Yb:YAG Gemstones, Light Blue Fantasy Cut Laser Garnets yap This Europium-doped fluorite is grownThese are faceted light blue ytterbium YAG, a type of blue laser garnet. The color varies from light greyish blue to more saturated blue green. Yb: YAG is an uncommon type of YAG, grown for use in some infrared lasers including ones used for high power engraving. While it is used in a variety of infrared laser systems it is surprisingly hard to actually get as industrial scrap this is because the material is usually annealed immediately after growth,
