However if blue is a secondary tone that is visually present, then the stone is categorized as an aquamarine. Another variety is yellow or golden beryl. This gem can run the color range from a pale sunshine yellow to a brilliant golden color. The stone is often referred to as Heliodor. This name comes from the Greek word for sun—Helio. It is also commonly referred to as golden or yellow beryl. The next color that is found in natural beryl is pink. This pink variety is usually a very soft baby pink and has a gem name of either pink beryl or morganite. The gemstone was discovered in 1910 on the coast of Madagascar. The prospecting adventure was funded by J.P. Morgan of New York City, so the discovery was named in his honor. This pink version of beryl owes its color to magnesium being present at the time of its birth. Morganite has since been discovered in California and Maine. The largest ever discovered pink beryl was discovered in Buckfield, Maine, in 1989. In recent years, some jewelry stores have started to market pink beryl (morganite) under the name “pink emerald.” This has been prohibited by the Federal Trade Commission as emerald is strictly defined as a green beryl variety with a very defined saturation level. The rarest form of beryl, rarer even than gem grade emerald, is the red variety commonly called bixbite or red beryl. This gem was first discovered in 1904 by Maynard Bixby in Utah. The dark, ruby red color of this gem is caused by an extremely high concentration of magnesium as the gem forms. This high concentration actually prohibits crystal growth and leads to highly included crystals. This red beryl is very expensive due to rarity and is usually only for collectors and museums.
