Physical properties
Hardness of 6.5 to 7 on the Mohs scale, vitreous to waxy luster, microcrystalline (cryptocrystalline) quartz structure, conchoidal fracture, specific gravity of 2.58 to 2.64. The specimen shown is dyed pink with white banding.
Formation & geological history
Formed by the deposition of silica from groundwater in the cavities of igneous and sedimentary rocks, typically over millions of years. Often artificially enhanced with dye for jewelry.
Uses & applications
Used primarily in jewelry, as pendants, cabochons, beads, and decorative ornamental items.
Geological facts
Agate is one of the most popular materials for tumbling and carving. The porous nature of chalcedony allows it to absorb artificial dyes easily, creating vibrant colors not typically found naturally in such intense shades.
Field identification & locations
Easily identified by its characteristic curved banding and waxy luster, though the bright pink color indicates it has been color-enhanced.
