One of one, and never again.

On iron pieces, the Widmanstätten pattern — the lattice of interlocking crystals revealed when the metal is cut and acid-etched — cannot be reproduced by any process on Earth; it only forms over millions of years of slow cooling in space. Iron and stony-iron samples are also strongly magnetic and noticeably dense for their size. Beyond that, every piece ships with a signed Certificate of Authenticity and is sourced under Emil’s IMCA membership (#4748).

No. Our certificates are signed, not numbered — each one names the meteorite, its classification and origin, and is signed by hand. The piece itself is the unique object; the certificate vouches for it.

Iron and stony-iron meteorites are metallic iron, so in damp air they can develop surface rust over time — it’s actually a sign the metal is genuine. The fix is simple: keep them dry. Store in low humidity, handle as little as possible (skin oils and sweat accelerate it), and wipe with a soft dry cloth. A silica-gel sachet in a display case keeps moisture at bay. Stony pieces like chondrites and tektites such as moldavite don’t rust at all.

Handle etched surfaces gently — they scratch easily — and ideally with clean, dry hands or cotton gloves, since fingerprints can mark the metal. Keep iron pieces somewhere dry and stable; avoid bathrooms, basements and sealed bags that trap moisture. Display boxes already solve most of this for you.

Yes. Every sample is a single, individual piece — cut, weighed and photographed on its own. What you see is the exact stone you receive; once it’s sold, that one is gone.

Muonionalusta we hunt ourselves in Swedish Lapland. The rest are chosen and verified from the strewnfields and finders who recover them — Sericho from Kenya, Imilac from the Atacama, Aletai from the Gobi, Campo del Cielo from South America, and lunar fragments from permitted recoveries. Moldavite is a tektite, not a meteorite — impact glass from the Czech Republic — and we always say so.
