Weird Yb:YAG Garnet Facet Rough, Experiment Gone Wrong Type:Brown, 7.7g Laser Alexandrite: An amazing material

Laser Alexandrite: An amazing material grown mostly for medical lasers

The tops are also very well shaped for cutting dice

The result is a larger boule of much higher quality

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

typically by soaking in a sugar solution and then exposing it to sulfuric acid which carbonizes the sugar

Weird Yb:YAG Garnet Facet Rough, Experiment Gone Wrong Type:Brown, 7.7g Laser Alexandrite: An amazing materialThis 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!
