Physical properties
Hardness: 6.5-7 Mohs; Color: Pink/Purple (dyed); Luster: Waxy to vitreous; Structure: Cryptocrystalline; Cleavage: None; Specific Gravity: 2.6
Formation & geological history
Formed in volcanic cavities or sedimentary rocks through the deposition of silica from groundwater. This specific piece is a thin slice that has been chemically dyed and polished.
Uses & applications
Primarily used for decorative purposes, coasters, jewelry pendants, and as metaphysical healing stones.
Geological facts
The pink color is not natural; agates are frequently porous enough to absorb synthetic pigments. If you were to soak this in acetone, the color might fade or leach out.
Field identification & locations
Identify by the characteristic concentric banding and waxy luster. Commonly sourced from Brazil. In the field, look for rounded nodules with a rough, 'cauliflower' exterior.
