Ce/Nd Laser YAG Pommel Stone Cut (32 ct) lumenite For instance a D20 cut

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

These are lab created sapphires which were grown for use as a sensor window in the F35 fighter jet but didn't meet spec

Though it is well known in the gem world it is also highly valued in the world of science and industry

) but sometimes they make mistakes

This is a zincite crystal that I faceted

Ce/Nd Laser YAG Pommel Stone Cut (32 ct) lumenite For instance a D20 cutThis 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
