Drusy & Opal Care
Clean the tiny crystals on the surface of the drusy quartz with unscented dishwashing detergent, water and a soft brush.
When a precious stone has tiny crystals formed on its surface, it is said to be drusy. When mineral and silica rich water gets into the porous area of a gem, it eventually cools and crystallization occurs, and this is how drusy is formed.
Drusy can form on just about any mineral substrate, but the gem-quality drusy quartz generally forms inside geodes–hollow rocks with crystalline structures inside. Brazil and Indonesia are major sources of drusy quartz.
Generally, white based and black based opals, if exposed to heat or stored in dry airtight places, including safety deposit boxes, can cause the opal to lose moisture and dehydrate. That is why we primarily sell Australian Boulder Opal. It comes carved in tact in the “mother matrix”, ironstone. This rock gives it an added base of protection even in storage. We also welcome Ethiopian Opal into the family of “more dehydration resistant” opals.
