However, morganite is relatively rare, which stands in the way of it becoming a jewelry stone. Heliodor, or golden beryl, is named after the greek words for sun helios and gift doron . The sunny yellow color of this beryl lives up to its name. Heliodor was discovered in Namibia in 1910 in a pegmatite that also produced aquamarine, which is also colored by iron. Heliodore is also found in Brazil and Madagascar.

The color is stoplight red. Unfortunately this deposit produces only a small quantity of this gem, and most of the gems produced are under a carat in size, and many have inclusions. Specimens that are over a carat and clean are fantastically rare and are priced as such. Colorless beryl, which is also known as goshenite, is also relatively rare. It is named after a deposit where it was found in Goshen, Massachusetts.
