£ 64.80
GENUINE ACHONDRITE DIOGENITE METEORITE – NWA 7831, WESTERN SAHARAThis exceptional specimen is a genuine NWA 7831 Diogenite meteorite, discovered
in the Western Sahara and classified as part of the Howardite–Eucrite–Diogenite (HED) clan. Carefully selected for quality and presentation, this is the exact piece you will receive, as shown in the photographs. Each specimen includes a Certificate of Authenticity with a lifetime guarantee, ensuring complete confidence in its extraterrestrial origin. METEORITE CLASSIFICATION & ASTEROIDAL ORIGINNWA 7831 is classified as an Achondrite, specifically a Diogenite, a rare and scientifically significant type of meteorite. Unlike common chondrites, achondrites are igneous rocks that formed through melting and differentiation processes on their parent body. Diogenites are believed to originate from the deep crust or upper mantle of the asteroid 4 Vesta, one of the largest bodies in the asteroid belt.These meteorites represent material that crystallised slowly beneath the surface of a differentiated planetary body, offering a direct glimpse into early planetary formation processes within our solar system. GEOLOGICAL COMPOSITION & MINERALOGYDiogenites are composed predominantly of orthopyroxene (low-calcium pyroxene), giving them their characteristic coarse crystalline texture. Many specimens, including NWA 7831, may also contain minor amounts of olivine, chromite, and plagioclase, depending on the specific sample.The structure of this meteorite reflects slow cooling deep within an asteroid, resulting in a granular, crystalline fabric that distinguishes it from volcanic eucrites or brecciated howardites. This makes diogenites especially prized among collectors and researchers alike. FORMATION & GEOLOGICAL SIGNIFICANCEFormed over 4.5 billion years ago, this meteorite dates back to the earliest stages of solar system evolution. It represents plutonic material, crystallised beneath the surface of its parent asteroid before being excavated by impact events and eventually delivered to Earth.Its geological history includes:
• Magmatic differentiation within a protoplanetary body
• Slow crystallisation in a subsurface environment
• Ejection through impact processes in the asteroid belt
• Terrestrial arrival following atmospheric entrySuch specimens provide invaluable insight into planetary crust formation and early solar system dynamics. MORPHOLOGY & SURFACE CHARACTERISTICSThis specimen displays the typical features associated with diogenites, including a dense, crystalline texture and subtle variations in tone due to mineral composition. Depending on the cut or natural surface, it may exhibit a granular or slightly brecciated appearance, with visible mineral grains under magnification.Each piece has been carefully chosen for its aesthetic and scientific value, making it ideal for both collectors and educational purposes. AUTHENTICITY & PRESENTATION
• 100% genuine meteorite specimen
• Includes Certificate of Authenticity (lifetime guarantee)
• Exact item shown in photographs – no stock images
• Professionally selected for quality and display appeal A RARE ADDITION TO ANY COLLECTIONDiogenite meteorites are significantly rarer than many other meteorite types, making NWA 7831 a desirable addition to any serious meteorite or mineral collection. Its connection to asteroid Vesta and its deep-crust origin make it not only visually striking but also scientifically important.Whether you are a seasoned collector, educator, or enthusiast of planetary science, this authentic diogenite meteorite offers a tangible piece of early solar system history.
