About Quant Service AI

A meteorite registry built on proof, not hype

Quant Service AI began in 2018 with a simple frustration: too many specimens sold with no provenance you could check. So we built the opposite.

The Quant Service AI study and specimen room

We are a small, specialist registry based in London, run by collectors who got tired of buying meteorites that arrived without a shred of documentation. Every specimen we handle is authenticated, classified and recorded before it is offered — and it ships to you with the paperwork that proves what it is.

Much of the meteorite trade runs on trust and good photographs alone, and plenty of it is honest. But an undocumented specimen is impossible to verify and easy to misrepresent, and the value of a meteorite lives as much in its provenance as in the rock. Quant Service AI exists to be the version where the record travels with the stone.

How we source

We buy from hunters and dealers who record where a specimen was found and cooperate with classification, and we favour material with a clear, lawful chain of custody. We turn down anonymous stones, however tempting, because a specimen with no history is a specimen we cannot honestly sell.

What we mean by a good specimen

Not necessarily the rarest or the most expensive. A good specimen is an honest, well-documented example of its kind — a £45 chondrite with visible chondrules and a real crust can be as satisfying, in its way, as a five-figure fragment of Mars. Each is measured against what it is and what it costs.

Our promises

Three rules we don’t break

We verify before we sell

No specimen is listed until its classification checks out against the Meteoritical Bulletin. If we cannot stand behind it, we do not stock it.

We document everything

Every piece leaves with its name, class, find data, mass and photographs — and we keep our own copy to re-issue if you lose yours.

We grade and price honestly

One clear grade, a fair band against real peers, and plain talk about weathering, rarity and care. We would rather lose a sale than oversell.
