Unfortunately I don't have an answer BUT, uncannily I have heard A LOT of good things about moldavite. A few months ago I went to a crystal store, asked one of the workers about any suggestions he had ... and this guy just went off ... he showed me his piece of Moldavite and started giving me this 10 minute speech on all the amazing powers and benefits of it. I was blown away at his enthusiasm. He even put it in my hand to let me feel its heat ... and I could actually feel it.

Seems to be legit ...
