Fantasy Cut GAGG Lumogarnets

These are fantasy cut GAGG lumogarnets.  Some also have a noticeable afterglow/phosphorescence.  Each is pictured individually.

GAGG is known for its incredible fluorescence which turns basically any higher energy radiation into vivid yellow light.  These fantasy cuts with their concave curved faces add an extra dimension to the stones, like staring into infinity.

Cerium GAGG is a material which has recently risen to prominence in industry but never been used as a gem until now. It is what we call a 'lumogarnet' - a lab created garnet with incredible fluorescence. It glows a bright yellow, slightly greener and brighter than already-bright Ce:YAG. This material is like an upgraded version of the classic GGG crossed with an aluminum garnet (like YAG and LuAG) to give it excellent hardness (8) while maintaining a high RI (1.9) and generally excellent gem properties.
