These pieces are natural quartz that have been treated with a thin metallic coating to create a vibrant purple iridescent finish, known as “aura quartz.” The treatment involves bonding metals such as titanium or platinum to the quartz surface, producing a rainbow-like effect while preserving the clarity and structure of the crystal.
Details:
- Material: Natural quartz (SiO₂) with metallic aura coating
- Form: Loose pieces, varying in size
- Appearance: Transparent to translucent quartz with a vivid purple iridescent sheen
- Formation: Quartz naturally crystallizes from silica-rich fluids; the aura effect is created artificially through vapor deposition of metals
- Physical Properties: Mohs hardness 7; vitreous luster; smooth, durable surface
- Educational Value: Demonstrates natural quartz crystallization alongside human-applied surface treatments that alter optical properties
These purple aura quartz pieces combine natural mineral structure with colorful visual effects, making them ideal for display, educational purposes, or collection.
