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.
