Drusy Quartz is rated at 7 on the Moh’s Scale of Hardness and is best suited for pendants, brooches, and earrings rather then rings and bracelets because of the concern of the Drusy being detached.
Drusy’s are gemstones 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. Drusy crystals went unnoticed in the jewelry world until recently, when they began appearing in the work of noted carvers and jewelry designers. The appeal is now starting to grow for Drusy Quartz jewelry as it displays a multitude of tiny crystals with a reflective surface reminiscent of sugar or snow.
The size and evenness of the crystal coverage are both important value factors when determining the quality and worth of Drusy Quartz items.
When ground water carrying dissolved silica is forced into a porous area of the rock, rapid cooling often occurs, causing the formation of tiny crystals on the surfaces or in cavities of the rock. The clear crystals often form on top of previously deposited minerals. This is called a drusy.
Titanium drusy is drusy that has been coated with titanium in a vacuum chamber. It produces a permanent metal coating in spectacular shades of dark blue, magenta or an iridescent white.
