Physical properties

Hardness: 6.5–7 (Mohs); Color: Hot pink (unnatural); Luster: Vitreous to waxy; Crystal Structure: Trigonal (microcrystalline); Cleavage: None; Fracture: Conchoidal; Specific Gravity: 2.58–2.64.

Formation & geological history

Formed as a primary mineral in volcanic and sedimentary environments through the deposition of silica. The intense pink color is achieved after extraction by soaking the porous stone in chemical dyes or through heat treatment and staining.

Uses & applications

Mostly used for costume jewelry, healing crystals, aquarium decor, and tumbled pocket stones for children and beginning collectors.

Geological facts

Agate and chalcedony are naturally porous, making them the most common minerals used for dyeing. Natural pink stones like Rose Quartz or Rhodochrosite rarely have this specific 'neon' or 'electric' pink hue.

Field identification & locations

Identify in the field by looking for translucent cryptocrystalline quartz; unnatural brightness or concentration of color in cracks or pits usually indicates dye. Commonly found naturally in Brazil or Uruguay before being processed.
