The stunning visual appeal of druzy quartz beads and pendants make them a great option for jewelry focals. Sometimes spelled druse or drusy, druzy is a layer of fine crystals that forms on the surface of rock fractures (most commonly quartz) over millions of years. While usually composed of clear crystal, druzy can also be composed of amethyst, citrine, or other naturally colored crystals. Druzy may also be enhanced to change its color, including by vacuum coating (a process that bonds a thin layer of metal to the surface of the crystal at a molecular level).
Drusy is delicate, and is best suited for applications like pendants and pins that will not receive a lot of wear. To clean, use warm, soapy water and a soft brush. Drusy quartz rates 7 on Moh's Scale of Hardness; to avoid scratching your other jewelry, gently wrap druzy in fabric when storing it.
