Opal Stones & Crystals
Opal is a form of silica that holds water in its structure, and not every opal flashes rainbow color. Common opal comes in soft pastel and earthy shades, while precious and fire opal show more vivid color. Shop opal stones in polished hearts, points, freeforms, spheres, slabs and tumbled stones, plus raw opal by the pound, cabochons and opal jewelry. Varieties include pink opal, pistachio green opal, purple opal, dendritic opal and Mexican fire opal. Keep opal away from sudden temperature changes and harsh cleaners.
