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 synthetic 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.
This material also glows in the dark, though the amount varies from piece to piece. They try hard to make sure it won't have any afterglow but mistakes do get made sometimes and these gems are the ones that didn't make the cut for whatever reason.
