Physical properties

Hardness: 6.5-7 Mohs; Color: Neon pink (artificially dyed); Luster: Vitreous to waxy; Crystal Structure: Hexagonal (trigonal); Cleavage: None; Specific Gravity: 2.58-2.64

Formation & geological history

Formed in cavities of volcanic rocks (like basalt) where silica-rich groundwater deposited layers of microcrystalline quartz over thousands of years. Natural agate is often millions of years old.

Uses & applications

Primarily used for decorative purposes, coasters, wind chimes, and beginner gemstone collections.

Geological facts

The intense pink color is achieves through a dyeing process where the porous layers of the agate absorb chemical dyes. Naturally pink agate is much paler and rare.

Field identification & locations

Identify in the field by searching inside volcanic geodes or river beds for nodules with concentric banding. To check for dye, look for concentrated color in cracks or uniform, unnatural saturation.
