Goldstone is manmade glass with flecks of copper suspended in it. Its invention occurred by accident in seventeenth-century Venice by the Miotti family. The glass is made in a reducing furnace with copper salts added, this smelts the copper salts back to copper, which then crystallizes.
As a healing stone, it is the stone of ambition and drive and has a gently uplifting quality. The metaphysical properties of copper are said to be the ability to aid the circulatory system, help strengthen bones and fight arthritis pain.
