Crystal Items : In India crystal is also called SPHATIK. The name quartz comes from the Saxon word querklufterz which means "cross vein ore." Crystal is from the Greek word krystallos, which means "ice,", due to the early Greek's belief that rock crystal formed from ice. There isn't just a single crystal that is all-powerful. Rather, there are many different crystals and minerals that can be used to heal and provide spiritual guidance. However, when most people think of healing crystals, they think of the clear quartz crystal. Many practitioners that use crystals and minerals for healing work would agree that the quartz crystal, in various shapes and sizes, is truly one of the most versatile and useful crystals the earth has to offer.
