Ce/Nd Laser YAG Pommel Stone Cut (32 ct) lumenite This is fluorite

This is fluorite

For instance a D20 cut has 5-fold symmetry and an 80 degree gear is needed to cut it

so it's an amazing gem in its own right instead of just trying to imitate diamonds

in laser science all corundum doped with chromium is considered ruby (in contrast to pink laser sapphire which is doped with titanium)

Ce/Nd Laser YAG Pommel Stone Cut (32 ct) lumenite This is fluoriteThis is a golden CeNd YAG laser garnet I faceted in my custom pommel stone design, which weighs in at 32 ct. It has a yellow base that shifts to orange in some lights and has dual fluorescence, glowing yellow green under blue and violet light and pale orange under 365nm long wave UV. I faceted this stone using our CutKit Mast. This is an unusual lab created garnet, YAG (yttrium aluminum garnet) doped with both cerium and neodymium. Neodymium makes YAG
