NWA 18045 Lunar Meteorite Specimen Official Lunar Melt Breccia Moon Meteorite

An authentic specimen of the officially classified Northwest Africa 18045 (NWA 18045) lunar meteorite, a rare Lunar Melt Breccia approved in Meteoritical Bulletin 114 in 2025. This remarkable meteorite represents genuine lunar material ejected from the Moon's surface during powerful impact events before eventually reaching Earth.

NWA 18045 belongs to the highly sought-after lunar melt breccia category — a rare class of Moon meteorites formed when intense impacts melted and brecciated portions of the lunar crust, creating a complex mixture of mineral and lithic fragments suspended within impact melt material.

Official Classification

Scientific Composition

Scientific analysis identified: impact melt textures, feldspathic melt matrix, anorthositic clasts, gabbroic and olivine-bearing lithologies, crystalline and glassy impact melt features, olivine, pyroxene, and plagioclase mineral assemblages, and accessory ilmenite and pink spinel.

Physical Characteristics

Official reports describe: weathered fusion crust, dark slightly vesicular melt matrix, visible melt schlieren textures, sub-angular and sub-rounded lithic clasts, and crystalline impact melt structures.

Ideal For

• Lunar meteorite collectors
• Advanced planetary science collections
• Impact melt breccia collectors
• Museum and educational displays
• Rare classified meteorite collections
• Space and Moon exploration enthusiasts

Lunar melt breccias are especially prized because they preserve evidence of ancient impact processes that shaped the lunar surface and crustal structure.

A genuine fragment of the Moon and one of the rarest natural collectibles available to collectors today.

Condition

Please review all photos carefully for overall condition, fusion crust, weathering, fractures, brecciation, and natural structural characteristics, as they are considered part of the description. Lunar meteorites are natural extraterrestrial objects and commonly display impact textures, fractures, and structural variation from lunar impacts and terrestrial recovery.
