You might be wondering "why is fluorite jewelry is so rare when it's so cool

We only managed to get a limited amount but we're going to do everything we can to secure a steady supply

Pure Er:YAG Rough, Erbium Color-Change Garnet Stone:Edge, 12.5×11.8×10.7mm, 5.02g This is facet rough ofThese 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.
