Goldstone is a man made gemstone that has been around since the European Rennaissance.
Early monks working at a glass factory near Venice, Italy were practicing alchemy when molten copper accidentally tipped into a molten glass container. This crystallized into thousands of tiny crystals and formed a melt with golden light sparkles. This is how the first goldstone came about.
