typically by soaking in a sugar solution and then exposing it to sulfuric acid which carbonizes the sugar
Colorless ZnS is grown for use for optics
and it has the highest brilliance and dispersion of any transparent gem material
I don't even know why they were experimenting with this unusual crystal--it has a higher density

Weird Yb:YAG Garnet Facet Rough, Experiment Gone Wrong Type:Brown, 7.7g typically by soaking in aThis 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!
