Physical properties

Hardness: 7 Mohs; Color: Purple/lavender concentrated in internal fractures; Luster: Vitreous to waxy; Texture: Spherical polish with visible spider-web surface fissures; Specific Gravity: 2.65.

Formation & geological history

Natural clear quartz is subjected to thermal shock (heating and rapid cooling) to create internal fractures, then submerged in dye which seeps into the cracks through capillary action.

Uses & applications

Decorative use, costume jewelry beads, metaphysical/healing practices, and educational samples for identifying treated minerals.

Geological facts

The 'crackle' effect is a form of intentional quench-crackling. While the base material is natural quartz, the color is entirely artificial and can sometimes fade if exposed to sunlight or chemicals.

Field identification & locations

Identify by looking for 'bleeding' of color into cracks or concentration of pigment in fractures rather than a solid crystal body. This appearance does not occur naturally in quartz.
