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.
