If we are talking April 8, 2011 at 8:07 am #5125 rrouchParticipant I disagree. If we are talking about clean, faceted gems, I vote for GRANDIDIERITE (one known specimen), MUSGRAVITE (8 known speciments), or SERENDIBITE (3 known speciments). I agree that Ruby is probably the most expensive consumer gem.
