Yellow Zircon

10/07/08 22:00 Filed in: Latest Cut Gems
Here's one I missed photographing the other night. It's a Zircon from Tanzania. These stones are kind of a root-beer brown color, but with just some gentile heating over the flame from an alcohol lamp they turn yellow. The more you heat them, the lighter the get. This one I just heated a bit. If you heat them too long, the will go colorless.
