First discovered around 1905 and named bixbite for collector and dealer Maynard Bixby, this rare variety of beryl was renamed because of the confusion with the mineral bixbyite as well "bixbite" having unflattering market appeal. (Much the same as the renaming of zoizite to tanzanite.) Red beryl is mined in the Wah-Wah mountains of southwestern Utah. Some refer to red beryl as red emerald, which many find confusing. Better to differentiate and recognize the varieties independently as well as the historical argument associating by definition the term emerald with the color green. |

While synthetic red beryl is rare, Russia has produced some. Natural stones are in limited supply and small sizes, commonly found in sizes under 1 carat. A collectors gem, red beryl is seldom found in sizes over 2 carats. |

Impurities of manganese are the coloring agent for this beryl whose RI is 1.564 - 1.574 and has a hardness of 7.5-8. Unlike other beryls, red beryl is found in magmatic rock formations in small crystals. Two phase and healed fracture inclusions are common. Concentric color zoning has also been found. The color of red beryl is resistant to heat. |
