The best rock crystal has the clarity and shimmer of water.Although colorless quartz is relatively common,large flawless specimens are not,which is why crystal balls these days are made of glass,not quartz.Rock crystal has often been used in jewelry,particularly carved pieces.Many stunning Art Deco jewelry designs featured the black and white quartz combination of rock crystal and onyx.Colorless quartz crystals have also become popular in jewelry due to the popularity of legends about the powers of quartz crystals.Many people believe that wearing quartz crystals benefits a person's health and spiritual well being.
