Digital Devil #7. The believe-it-or-not story of Australia's Lenny Cram and his opal mine in a mason jar.

Installment #6 of my Digital Devil column, which discusses the introduction of HPHT diamonds into the market by Lazare Kaplan Inc. This one kicked up quite a stir. See the comments at the end.

Digital Devil #5, where I transition from hard-nosed gemological gumshoe to lamenting the lack of romance and appreciation of beauty in gemology.

Digital Devil #3. This column is for both those who know about the web, as well as them that have yet to understand its power.

Digital Devil #2. It took me a while to realize that the editor wanted me to write about gems.

Digital Devil #1: The fights between gem dealers and gemologists are legendary, with each side looking down upon the other. It's truly dog against dog.
