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.
