Physical properties
Hardness: 6-7 (Mohs scale); Color: Dark fusion crust with light gray to white clasts in a dark matrix; Luster: Sub-vitreous to dull; Crystal Structure: Fragmental (brecciated); Cleavage: None; Specific Gravity: Approx 2.7-3.1
Formation & geological history
Formed on the Moon's surface from high-velocity impacts that shattered and consolidated lunar highlands rocks. These fragments were later ejected from the Moon by another impact and fell to Earth. Geological age of source rocks is often 3-4.5 billion years.
Uses & applications
Scientific research, planetary study, high-end private collection, and occasionally used in luxury jewelry or watch faces.
Geological facts
Lunar meteorites are rarer than gold or diamonds. This specimen shows a classic 'fusion crust'—the thin, dark, cracked outer layer formed by intense heat as the rock entered Earth's atmosphere.
Field identification & locations
Identify by looking for a thin fusion crust, the presence of various angular rock clasts (brecciation), and a lack of significant iron (unlike common nickel-iron meteorites). Often found in desert regions like North Africa or Antarctica where dark rocks stand out.
