BIXBITE     Gem Species:  BERYL     Hardness:  7.5     Density:  2.72     RI:  1.58
 Red Beryl is only found in Utah. These are incredibly rare and the mines produce so few annually that no company has been consistently profitable. This leads to closures and significant value increases. They are so rare that clean material over 2mm is extremely rare and anything with any clarity is super valuable. Our material is old and priced accordingly. We cannot get material at these prices and although we've sold many, we have a few left we are offering up on Auction.
