Drusy quartz, silicon dioxide, is most commonly clear or whitish, and can resemble glittering sugar or snow crystals.
Because of its sparkling appearance, druse is sometimes used in jewelry making. Both the glittering effect of the tiny crystals and the color of the base mineral are factors when selecting druse for this purpose. Druse, also known as drusy or druzy, is used with a variety of natural gemstones including agate, crystallline quartz and many more. Druse can be colored by electroplating, a process similar to rhodium application, giving the stone a fancy look, and a brighter appearance than is natural.
