Also know as Red Emerald and Scarlet Emerald, Bixbite is regarded by many as the rarest member of the Beryl family of gemstones. The gem is named in honour of the legendary mineralogist Maynard Bixby (1853-1935) of Utah, America, who was believed to have first discovered the gem in 1904.
Many gems marketed as Bixbite are in fact a different gem known as Pezzottaite. The confusion arises as both their chemical construction and appearance are almost identical. Bixbite, however, is currently only
Mined in two locations on the planet: the Wah Wah Mountains in Utah, America and also in the Catron and Sierra Counties within New Mexico. Pezzottaite, on the other hand, was first discovered in Madagascar in 2002, although the mines are now said to be depleted; luckily there has been a recent discovery in Afghanistan.
The gem’s stunning red appearance is due to the presence of manganese, and even though the gem is normally heavily included and at best translucent, many collectors regard the gem as a greater acquisition than Ruby.
