Physical properties
Hardness: 6.5-7 (Mohs scale). Color: Translucent green with mossy inclusions. Luster: Vitreous to waxy. Crystal Structure: Hexagonal (microcrystalline). Cleavage: None. Specific Gravity: 2.58-2.64.
Formation & geological history
Formed in volcanic rock cavities or sedimentary rocks through the deposition of silica from groundwater. The green color often comes from impurities like iron or manganese.
Uses & applications
A popular gemstone for jewelry (pendants, rings), decorative ornaments, and used in precision tools like mortars and pestles due to its hardness.
Geological facts
Agate is a variety of chalcedony. Moss agate is often called the 'gardener's stone' and is unique because it contains dendritic inclusions that look like organic plant matter.
Field identification & locations
Identify by its waxy luster, translucency, and lack of visible crystals. It is commonly found in riverbeds or volcanic regions like Brazil, India, and the USA (Pacific Northwest).
