Description
Colorless beryl is called goshenite. The name comes from Goshen, Massachusetts, where it was originally discovered. Since all these color varieties are caused by impurities and pure beryl is colorless, it might be tempting to assume that goshenite is the purest variety of beryl. However, several elements can act as inhibitors to the color of turquoise, and so this assumption is not always true. The name goshenite is reportedly on its way to extinction, yet it is still commonly used in the gemstone market. Goshenite is found in some quantity in almost all beryl localities. Historically, goshenite was used for making glasses and lenses because of its transparency. Today, it is most commonly used for gemstone purposes and also as a source of beryllium. The gem value of goshenite is relatively low. However, goshenite can be colored yellow, green, pink, blue, and in intermediate colors by irradiating it with high-energy particles. The resulting color depends on the content of Ca, Sc, Ti, V, Fe, Co and impurities
