Goldstone was invented by accident in the 19th century by an Italian monk who dropped a pan of copper shavings into a vat of molten tinted glass. After the glass cooled, it shimmered like gold! Goldstone is a man-made stone comprised of melted glass, containing tiny crystals of glittering metallic copper that give it its radiant sparkle. The brown color of Goldstone is great for grounding energy. The indigo color of Blue Goldstone makes it an excellent tool for restoring and balancing the Third Eye Chakra, as it promotes intuition. The copper within Goldstone helps to conduct energy and align the meridians.
