This specimen is from the famous Mundrabilla iron meteorite from Western Australia, one of the largest meteorite finds documented on Earth, with a total known weight of about 24 metric tons. Classified as an IAB medium octahedrite, Mundrabilla represents material from the metallic core region of a long‑destroyed asteroid that once orbited in the main asteroid belt before being redirected toward Earth.
The meteorite itself is composed predominantly of an iron‑nickel alloy (around two‑thirds to three‑quarters metal by weight) with about 7–8% nickel and minor cobalt. These phases crystallised as the parent body cooled over millions of years, producing the internal octahedrite structure and giving Mundrabilla its distinctive metallic sheen.
This individual specimen weighs 35 grams and measures approximately 2.9cm x 2.3cm x 2cm. Found as part of the Mundrabilla strewn field first recognised in 1911, it is from an unobserved fall that has probably lain for many thousands of years on the Nullarbor Plain before discovery. Radiometric studies of iron meteorites indicate that material like Mundrabilla formed about 4.5–4.6 billion years ago, making this piece older than any terrestrial rock and contemporaneous with the birth of the solar system.
This Mundrabilla iron meteorite comes with a certificate of authenticity, making it suitable for serious collectors, educators, or anyone wanting a scientifically important and well‑documented meteorite from one of the world’s great iron meteorite finds. It also comes with a membrane floating display case.
Package includes: meteorite specimen, certificate of authenticity, collectors display case
