Physical properties

Formation & geological history

Created by heating natural clear quartz and then quenching it in cold liquid (dye). This 'thermal shock' causes internal fracturing while keeping the specimen intact. The dye then seeps into these internal cracks.

Uses & applications

Used primarily in costume jewelry, decorative home accents, tumbled stones, and 'healing crystal' collections.

Geological facts

Naturally occurring blue quartz exists, but it is typically a dull, grayish-blue. The vibrant, neon color seen in this specimen is a sure sign of human-made color enhancement. The internal network of tiny cracks gives it the name 'crackle quartz.'

Field identification & locations

Identify by looking at color distribution; the blue pigment is concentrated in spider-web patterned veins rather than being uniform throughout the body of the crystal. Commonly sold in gift shops and crystal boutiques.
