Pure Er:YAG Rough, Erbium Color-Change Garnet

Pure Er:YAG Rough, Erbium Color-Change GarnetThese are facet rough of erbium doped YAG, a lab grown garnet used in lasers for both medicine and industry. Erbium YAG has a very obvious color change between different light sources. Under sunlight and cool LEDs it's a nice orange, but it shifts easily, changing color between Cool LEDs (orange), Warm LEDs (yellow), CFL (strawberry pink), and OLED (magenta) as well as under fluorescent lighting and OLED illumination. Sunlight shows an orangeish pink.

a type of hyperfluorescent lab created garnet which were produced for use as scintillators in PET scanners

We have sent samples of each size to Jostens and verified with their gemologist that these meet their custom stone specifications

even an oddball andalusite

These are violet in normal light and turn pure colorless under fluorescent illumination (like a CFL bulb)

but still works very well

These are specimens of Trinitite

These are our special

This piece has a few inclusions but they seem to be concentrated on the edges

These are fantasy cut pink laser sapphires

These are lab grown moissanites faceted in a custom glittery 'hypercube' design

While conventional material is merely ridiculously bright this material upgrades it to 'bonkers' levels with an even brighter glow

unlike what certain acid-shrunken retailers might charge for it
