Physical properties

Hardness: 6.5-7 (Mohs); Color: Natural white/gray banded with artificial neon pink dye; Luster: Vitreous to waxy; Structure: Microcrystalline (trigonal system); Cleavage: None; Fracture: Conchoidal.

Formation & geological history

Formed as volcanic gas bubbles (vesicles) fill with silica-rich groundwater over millions of years. This specimen has been sliced, polished, and artificially dyed to enhance color.

Uses & applications

Primarily used for decorative purposes, coasters, jewelry making, wind chimes, and as a educational/collector specimen for beginners.

Geological facts

Agate is a variety of chalcedony. The bands are formed by alternating layers of different silica minerals. While agates occur naturally in many colors, the vibrant 'hot pink' seen here is achieve through chemical dyeing and heating.

Field identification & locations

Identify by characteristic concentric banding and high hardness. Found globally, especially in Brazil and Uruguay. Collectors should look for natural patterns through the dye.
