Physical properties

Formation & geological history

Likely formed as small quartz crystals lining a cavity or coating a surface as silica-rich water deposited quartz. The specimen’s age and geological setting cannot be determined from the image.

Uses & applications

Small druzy pieces are collected or used in jewelry and decorative settings; this fragment appears modest in size and finish.

Geological facts

“Druzy” describes a surface covered in many tiny crystals, rather than a distinct mineral species.

Field identification & locations

Look for a dense coating of glittering, pointed crystals; quartz should scratch glass and resist scratching by a steel knife. Druzy quartz occurs worldwide in cavities and veins, but the specimen’s locality is unknown.
