Druzy crystal is a configuration of many tiny sparkling crystals on the surface of a bulky crystalline body. This type usually grows over another matrix, but it may or may not be in contact the matrix afterward.For example, Druzy Quartz can grow over agate or any other colored matrix. But building this crystalline form is not only a feature of Quartz. Minerals like calcite, malachite, dolomite, and garnet are also found as Druzy stones.
