TGG Lab Garnets, Rare Lab Garnet from High Tech Lasers

TGG Lab Garnets, Rare Lab Garnet from High Tech LasersThese are faceted terbium gallium garnet aka TGG. Each is labelled with its carat weight and letter in the photo and they can be purchased individually. TGG is a very cool synthetic material. It has the same structure as a natural garnet, but has a composition that would never be possible in nature. The result is a bright and very dispersive gem with optical properties similar to diamond (cubic crystal structure with a lower RI but the same dispersion

I cut this one myself in my 'Red Stone of Aja' design

In theory a laser crystal cut from one of these very same crystals could be on mars in a few years

and has its own distinct charm

aka silicon carbide

There are numerous sensors on the bottom of an F35 that allow for a 365 degree view in a wide spectral range

These are a mixture of rejected material (likely for surface chips or maybe minor optical misalignments) and cores/wafers that just didn't get used before the factory closed

The fluorescence really is crazy--even normal room lights will make a LuAG gem fluoresce

brighter than the already-ridiculously-bright Ce:YAG

It is ideal for use in jewelry

what are sometimes called 'dogteeth' by sapphire miners

for identifying gemstones and minerals

particularly its outrageously strong green fluorescence which makes it glow when exposed to sunlight and even some indoor light
