Weird Yb:YAG Garnet Facet Rough, Experiment Gone Wrong Type:Brown, 7.7g Normally you'd cut windows out

Normally you'd cut windows out of a big round boule grown by HEM or Kyropoulos but the shape really isn't conducive to larger flat shapes

The color shifts from pink to orange and often looks golden on camera for some reason

It was discovered that trace rare earths - particularly europium - are responsible for this wonderful glow

and it has the highest brilliance and dispersion of any transparent gem material

Lumenite™ is a monocrystal of strontium aluminate

Weird Yb:YAG Garnet Facet Rough, Experiment Gone Wrong Type:Brown, 7.7g Normally you'd cut windows outThis is facet rough of weird mutated Yb: YAG. We tried to have it grown, it usually comes out a vivid blue green, but this one went wrong in the process. It has a combination of browns, yellows, greens, and occasional blue, giving more of a pondwater set of colors instead of the typical deep aqua blue you get from Yb: YAG. Since this was done by accident we don't know if we'll have more, but the colors are neat!
