Mercury Meteorite NWA 7325 Rare Planetary Meteorite 1-3mm Achondrite Space Rock Specimen

Description

Rare Mercury Meteorite NWA 7325 Planetary Achondrite Specimen

This listing features a genuine fragment of the rare planetary meteorite NWA 7325, widely regarded as one of the most unusual and scientifically significant meteorites discovered in recent decades. NWA 7325 is believed to originate from Mercury or a Mercury-like differentiated planetary body, making it one of the closest known materials available on Earth from the innermost planet of our solar system.

The specimen offered here is a carefully selected meteorite fragment measuring approximately 1–3 mm, making it a highly collectible micro specimen of a scientifically important planetary meteorite. The photographs in the listing show the exact meteorite specimen you will receive.

This meteorite is a genuine extraterrestrial specimen and includes a Certificate of Authenticity with a lifetime guarantee card, confirming its authenticity and origin.

Full sizing can be seen in the listing photographs.

Meteorite Classification and Scientific Identification

NWA 7325 is classified as a primitive achondrite meteorite, a rare type of igneous space rock formed on a differentiated planetary body. Unlike primitive chondrite meteorites that formed directly from the early solar nebula, achondrites formed from melted and recrystallised rock on planetary crusts or mantles.

Meteorite classification details:

• Meteorite Name: NWA 7325
• Type: Achondrite
• Group: Ungrouped primitive achondrite
• Discovery Region: Northwest Africa
• Official Registry: Meteoritical Bulletin Database

The meteorite was formally studied and recognised by the Meteoritical Society, the international authority responsible for cataloguing and classifying meteorites worldwide.

Since its discovery, NWA 7325 has attracted significant attention from planetary scientists due to its highly unusual chemistry and mineral composition.

Mineralogy and Geological Formation

The composition of NWA 7325 is dominated by magnesium-rich orthopyroxene minerals, particularly enstatite, along with minor accessory minerals. This mineral assemblage indicates formation under extremely oxygen-poor (highly reduced) conditions, a characteristic believed to match the crustal chemistry of Mercury.

Key geological characteristics include:

• High magnesium content relative to most meteorites
• Extremely low iron concentration
• Dominance of orthopyroxene crystals
• Coarse crystalline igneous structure
• Unique oxygen isotope signature

These characteristics suggest that the meteorite formed through igneous differentiation on a planetary crust, where molten rock cooled and crystallised into solid minerals.

The chemistry of NWA 7325 is unlike most known meteorites and has drawn comparisons with data collected by the NASA MESSENGER spacecraft, which studied Mercury’s surface composition.

Possible Origin from Planet Mercury

One of the most fascinating aspects of NWA 7325 is its potential connection to Mercury, the smallest and innermost planet in the solar system.

Mercury’s surface is known to contain magnesium-rich silicate minerals, similar to those found within this meteorite. Because Mercury lies deep within the Sun’s gravitational well, meteorites originating from the planet are thought to be extremely rare, requiring powerful impact events to eject material into space.

Although NWA 7325 is officially classified as an ungrouped achondrite, many researchers consider it one of the best candidates for a Mercurian meteorite or material from a planet with a similar crustal composition.

Fragments of this meteorite therefore represent some of the rarest planetary materials available to collectors.

Appearance and Natural Characteristics

Despite its small size of 1–3 mm, NWA 7325 fragments display natural mineral textures and colours that reflect their igneous origin.

Typical features may include:

• Natural crystalline surfaces
• Angular fragment shapes resulting from atmospheric entry fragmentation
• Mineral textures reflecting pyroxene-rich composition
• Desert weathering patina from Sahara exposure

Meteorites recovered in desert environments are often well preserved due to the dry climate, which helps protect the mineral structure over long periods of time.

A Genuine Planetary Meteorite for Collectors

Planetary meteorites originating from differentiated bodies are among the most sought-after specimens in meteorite collecting. Material potentially originating from Mercury is exceptionally rare and represents a fascinating piece of planetary science.

Key features of this specimen include:

• Genuine NWA 7325 planetary meteorite fragment
• Rare primitive achondrite meteorite
• Potential Mercury planetary crust origin
• Specimen size approximately 1–3 mm
• Registered within the Meteoritical Bulletin Database
• Photographs show the exact meteorite specimen you will receive
• Supplied with a Certificate of Authenticity and lifetime guarantee

This remarkable meteorite fragment makes an excellent addition to meteorite collections, planetary science displays, space rock collections, and educational natural history collections, offering a tangible fragment of material formed during the earliest stages of planetary formation within our solar system.
