Formation & geological history
Formed as a secondary mineral by the action of phosphate-bearing waters on aluminous rocks at low temperatures. Commonly found as nodules, crusts, or vein fillings in aluminum-rich sedimentary rocks.
Uses & applications
Primarily used as a gemstone for jewelry (cabochons) and as a decorative stone for collectors.
Geological facts
It is often mistaken for turquoise but contains aluminum instead of copper. It was named after Variscia, the historical name of a district in Saxony, Germany, where it was first discovered.
Field identification & locations
Identify by its distinctive pistachio-green color and relative softness compared to quartz. Commonly found in Utah (USA), Germany, and Australia. Collectors look for vibrant colors and interesting matrix patterns.
