Physical properties

Hardness: 7 (Mohs scale); Color: Neon or electric blue with internal fractures; Luster: Vitreous; Crystal Structure: Trigonal/Hexagonal; Cleavage: None/Conchoidal fracture; Specific Gravity: 2.65.

Formation & geological history

Formed through a heat-treating and quenching process: natural clear quartz is heated to high temperatures and then plunged into cold liquid (water or dye), causing thermal shock and internal shattering. These cracks are then filled with colored dyes.

Uses & applications

Primarily used for decorative purposes, costume jewelry, healing crystals, and as affordable pocket stones for collectors.

Geological facts

Natural quartz does not occur in this specific neon blue color with these types of internal fractures. The 'crackle' effect is entirely man-made to increase the visual interest of low-grade milky or clear quartz.

Field identification & locations

Identify by looking for 'spider-web' fracture patterns and color concentration within the cracks. Natural blue minerals like Sodalite or Lapis Lazuli lack this vitreous transparency and crackle texture. Commonly found in gift shops globally.
