Description
The word druse (also known as drusy or druzy) refers to a mass of small crystals ("crystal druse"). These crystal formations, or clusters, can be formed by many different minerals. The mineral types and shapes of crystals formed depend on the composition of the fluid. Crystal size is a function of fluid temperature and pressure. A druzy is a cluster of small mineral crystals that forms on the surface of another rock. There are many types of druzy, as there are many types of minerals. Each type of druzy has specific characteristics, such as crystal size, luster, and color. Quartz is one of the most common types of druzy due to the prevalence of silica worldwide. Regardless of the mineral that forms the druzy, the overall appearance usually resembles that of sugar. The small crystals are considered beautiful because, like large gemstones, they sparkle and catch light rays.
