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.
