Drusy quartz is a stone material that is relatively royal and beautiful when used in jewelry. It is a popular choice because of its sparkle and color and can readily be cut into interesting and unusual shapes. Drusy is a gemstone with a natural surface texture much like fine sugar crystals that formed on the Quartz by the phenomena of micro-crystalline facets millions of years ago. This natural Drusy Quartz gets its spectacular iridescent finish by a sophisticated Azotic coating treatment.   Care & Cleaning: Drusy Quartz can be cleaned using warm soapy water and a soft brush. As with most gemstones, Drusy Quartz should be kept away from household chemicals and from prolonged exposure to extremes of heat as this can cause damage or permanent changes to its appearance. Drusy Quartz should be kept in a fabric-lined box away from other jewelry items in order to avoid damage / scratching.
