Physical properties
Hardness: 6.5-7 Mohs; Color: Dark green with red speckles; Luster: Vitreous to waxy; Crystal structure: Trigonal/Hexagonal; Cleavage: None (Conchoidal fracture); Specific Gravity: 2.63-2.65
Formation & geological history
Formed in relatively cool temperatures via precipitation from silica-rich groundwater into cavities in other rocks. Red inclusions are iron oxide (hematite). Many specimens date back millions of years.
Uses & applications
Primarily used in jewelry (cabochons), signet rings, carvings, and as a birthstone for March. Also popular as a healing crystal in some cultures.
Geological facts
Legend says the red spots represent the blood of Christ. In ancient times, it was believed to give the wearer the power to stop hemorrhages and control the weather.
Field identification & locations
Identify by the characteristic dark green jasper base with distinct red blotches. Often found in riverbeds as water-worn pebbles. Common locations include India, Brazil, Australia, and parts of the USA (California, Nevada).
