Since all the varieties of beryl are based on coloration from variations in chemistry, it could be assumed that goshenite is the purest variety of beryl. However, there are several elements that can act as color inhibitors so this assumption may not always be true. Goshenite is found to some extent in almost all beryl localities.
In the past, goshenite was used for manufacturing eyeglasses and lenses because of its transparency. Nowadays, it is most commonly used for gemstone purposes but it’s actually more of a collector stone.
