Pezzottaite--6.9 x 5.1 mm. 1.15 cts. Pezzottaite was once thought to be a red beryl (bixbite). It is still often confused with, and sold as, bixbite. Soon after it came out, it was found not to be beryl, but a new rare mineral, though not as rare as bixbite. The color looks like a less saturated bixbite, but tends to have a slight orange undertone and doesn't approach the intense raspberry red of bixbite. This specimen from Madagascar (a second source has since been identified in Pakistan).
