Physical properties
Hardness: 4-6 (Mohs). Color: Black to dark brown fusion crust. Luster: Dull to sub-metallic. Texture: Regmaglypts (thumbprint-like indentations). Density: High (heavier than terrestrial rocks). Magnetic response: Usually strong.
Formation & geological history
Formed from the solar nebula 4.5 billion years ago. These are remnants of the early solar system that were never integrated into a planet. They fall to Earth after surviving atmospheric entry, which creates the scorched fusion crust.
Uses & applications
Scientific research, private collection, and occasionally used in custom jewelry (slices).
Geological facts
Chondrites contain small spherical grains called chondrules, which were once molten droplets in space. They are the oldest solid materials in the solar system.
Field identification & locations
Identify by checking for a dark, thin fusion crust, high density for its size, and magnetism. Look for regmaglypts on the surface. Collectors often use a 'window' grind to see interior chondrules or nickel-iron flakes.
