Physical properties

Hardness: 7 Mohs; Color: Electric blue (unnatural); Luster: Vitreous; Structure: Hexagonal; Specific Gravity: 2.65; Highly fractured appearance.

Formation & geological history

Natural quartz is heated then quickly quenched in cold water to create internal fractures (thermal shock), which are then filled with blue dye.

Uses & applications

Decorative use, metaphysical collections, and inexpensive jewelry like beads or wire-wrapped pendants.

Geological facts

The 'crackle' effect is a human-induced thermal shock. In natural form, quartz would not have this density of uniform fractures or such vivid localized pigment concentration.

Field identification & locations

Identify by looking for dye pools within the fractures and a color that appears too intense to be natural. Natural blue minerals like Celestite are much softer and lack these internal cracks.
