Physical properties

Hardness: 6.5-7, Color: Light blue with white patterns, Luster: Vitreous to waxy, Crystal structure: Cryptocrystalline

Formation & geological history

Forms in cavities of volcanic rocks through the deposition of silica-rich fluids over time.

Uses & applications

Commonly used in jewelry, cabochons, and as a healing/metaphysical stone.

Geological facts

Agate is a variety of chalcedony characterized by its fineness of grain and brightness of color.

Field identification & locations

Identifiable by its distinct banding or patterned appearance (though this piece is more mottled), waxy luster, and hardness. Often found in places like Namibia, Brazil, and India.
