Faceted GAGG Jewelry (Earrings and Pendants of Yellow Gadolinium Aluminum Gallium Garnet: Cerium)

These sterling silver earrings and pendants are cut from GAGG jewelry!  While they have varying amounts of visible yellow afterglow, it isn't extreme enough to be 'high glow' material.  You'll see it in a pitch black room after UV charging but don't expect much beyond that.

Note some of the stones have bubbles or other imperfections--these typically contribute to the phosphorescence.

GAGG is a type of hyperfluorescent lab created garnet produced for use as scintillators in PET scanners, CAT scanners or similar devices.  

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.
