It is named after the place where it was first discovered in the town of "Goshen" in Massachusetts, USA. The stone features high hardness, making it scratch-resistant and ideal for use in jewelry. Despite lacking the brilliance of diamonds, its exceptional clarity made it a historic choice for making eyeglass lenses before the development of modern glass manufacturing. Today, collectors and enthusiasts value it as a natural and elegant alternative to transparent stones, and it remains an important industrial source for extracting the element beryllium.
