Metal coated druzy, gold druzy, platinum druzy, titanium druzy, drusy.
Druzy refers to a blanket of tiny, sparkling crystals often found inside a geode or an agate. The sparkling appearance of druzy is like that of spilled salt or sugar. The formation of the tiny crystals occurs after molten rock begins to quickly cool, trapping gasses within it as it solidifies.
Plated druzy gets it glitzy looks from a process known as vapor-coating. Vapor-coating begins in a vacuum chamber. The high-karat gold (or platinum, titanium or silver) is converted to a vapor and then mixed with oxygen. The gold-oxygen vapor settles on the crystals of the druzy and bonds with them at the molecular level.
