Physical properties

Hardness: 6.5-7 on Mohs scale; Color: Artificially dyed bright pink/magenta; Luster: Vitreous to waxy; Crystal Structure: Trigonal (microcrystalline); Cleavage: None; Specific Gravity: 2.58-2.64.

Formation & geological history

Formed as nodules in volcanic rocks or ancient lavas, where silica-rich groundwater fills cavities. The 'crackle' effect is often achieved by heating the stone and rapidly cooling it, followed by dye infusion to saturate the internal fractures.

Uses & applications

Primarily used for decorative purposes, costume jewelry, tumbled stones for metaphysical use, and lapidary art.

Geological facts

Natural agate rarely occurs in these vibrant neon pink shades; most specimens of this color in the gemstone trade have been chemically dyed. Agate is named after the Achates River in Sicily.

Field identification & locations

Identify by looking for 'spiderweb' fracture patterns (quench-crackling) and unnatural color concentration in cracks. Commonly found in Brazil, Uruguay, and India before being processed for the market.
