Red Beryl was first discovered in 1904 in the Thomas Range in Juab County, Utah in a rhyoloite rock and happens to be one of the rarest forms of all beryls. It was discovered by Maynard Bixby. But the quality of red beryl was not very good at that time. Better quality red beryls which can be used as gemstones were found only in the latter part of 1950’s in the Wah Wah Mountains located in Beaver County. Red beryl with best gem qualities can be found only in this part of the world where mining is carried out on a regular basis. The largest red beryl in the world weighs around 54 carats.
Aquamarines and emeralds are all different types of red beryl. Red beryls are crystals which are hexagonal in shape and bits and parts of other elements are also found in these precious stones. Its refractive index is 1.564-1.574 and the specific gravity is 2.66-2.70. They are usually 2 to 10 mm long.
It is believed that red beryls are formed when gases and vapors of high temperature are released when the rhyolite burning rocks are cooled down. Red beryl develops under temperatures as high as 300 to 650 degree Celsius.
