Goshenite: Background and Summary
Goshenite is a colorless variety of beryl, a mineral that belongs to the cyclosilicate family. It is named after the town of Goshen in western Massachusetts, where it was first discovered in 1806. Goshenite is often found in association with other beryl varieties such as emerald, aquamarine, and morganite.Goshenite is usually transparent and has a vitreous luster. It has a hardness of 7.5 to 8 on the Mohs scale, which makes it relatively hard and durable. Its specific gravity ranges from 2.6 to 2.8, which is slightly lower than that of emerald and aquamarine. Goshenite has a hexagonal crystal structure and typically occurs in prismatic or tabular crystals.
Goshenite has several uses in the jewelry industry. It is often used as a diamond substitute in engagement rings and other pieces of jewelry. Goshenite can also be used as a gemstone in its own right, especially when it has a high clarity and brilliance. However, since goshenite is relatively common and lacks the distinctive color of other beryl varieties, it is not as popular as emerald or aquamarine.
