Moss Agate and Druzy Quartz Carving

Physical Properties

Hardness: 6.5-7 (Mohs scale), Color: Green (chlorite inclusions) and white/grey translucent banding, Luster: Vitreous to waxy, Crystal Structure: Hexagonal (cryptocrystalline), Cleavage: None/Conchoidal

Formation & Geological History

Formed in cavities and fissures in volcanic rock through the deposition of silica-rich groundwater. Moss agate forms as mineral filaments (often chlorite or manganese) are trapped within the silica as it solidifies.

Uses & Applications

Decorative carvings, jewelry, lapidary arts, and metaphysical collections.

Geological Facts

Moss agate is not technically a true 'agate' because it lacks the classic concentric banding; it is a variety of chalcedony with dendritic or moss-like inclusions. This specific piece is carved into a 'goddess torso' shape.

Field Identification & Locations

Identified by its distinctive moss-like green patterns and translucent white chalcedony base. Often found in Brazil, India, and the United States (Montana). In the field, look for nodules with a waxy exterior.
