Beryl is colorless in pure form, but different element impurities tint it in wide variety of colors in nature. It has a vitreous (glassy) luster and can be transparent or translucent. Members of the beryl family include the aquamarine, emerald, and morganite. Yellow, blue and green beryls are also used in jewelry. Yellow beryl is usually not heat-treated.
The origin of the name beryl is thought to derive from the Sanskrit word 'veruliyam,' an old term for the gemstone chrysoberyl (but beryl and chrysoberyl are not the same). It is also believed to derive from the Greek Word 'beryllos' which means crystal and was originally applied to all green gemstones, but was later used for beryl alone.
Legend says that beryl was once used to ward off demons and evil spirits and will protect the wearer from danger while traveling. Other legends also indicate that beryl can be used to bring good luck, cheerfulness, energy, and can give eternal youthfulness.
Beryl has a 7.5 to 8 Mohs hardness rating and is a durable stone ideal for all jewelry purposes.
