“Druzy” is a mineral with a coating of tiny crystals and is mined from caves in southern Brazil. Geodes with druzy are a small percentage of the mined stones and ones with fine crystal quality are even rarer. Once the stones have been selected for cutting, the outer rock is removed with as many as 18 saw cuts, leaving pieces just thin enough to be set in jewelry. Copper, gold, platinum and titanium druzy occur when a rare high quality crystalline is vaporized in a vacuum chamber, leaving behind a permanent coating of the chosen metal. Druzy quartz is fragile. Natural variations and imperfections are characteristic of the stones and should not be considered flaws.
