Cut stones, rough material and mineral specimens — sourced worldwide for collectors, jewellers and private clients. Six hundred and seventy-two kinds of stone described, each with its gemmology written out.
Nothing here was invented.
It was found — and then chosen.
A stone is worth different money and suits a different buyer depending on how far along it is. We deal in all three, and we say honestly which one your job needs.
Faceted and polished, ready to set. Graded by hand, with the locality stated before you pay.

Uncut crystal and nodule for cutting, carving or collection. Cheaper per gram, and the yield is yours to judge.
Explore rough →
Crystals, geodes and clusters left whole, priced as objects rather than by weight. Locality is most of the value.

We believe the better culture — for private buyers and distributors alike — is to have gems cut to order by people who do nothing else, and then to have the jewel made by a jeweller you already trust. Every craft has its own art.
Reading a rough crystal — where the colour sits, where it is clean, what it will actually yield — is a trade of its own. That is the part we do, and we tell you what we see in a stone before you commit to it.
Tell us the species, the colour, the weight and the shape. It is cut to that brief by a cutter who works that material every day. A cutter who only facets will not carve, and a carver will not calibrate.
The stone arrives loose and it is yours outright — you know exactly what you paid for it, and no setting is hiding anything. Take it to the goldsmith you trust and have the piece made the way you want it.
Every stage of a gem is a separate craft. We would rather be excellent at one of them than adequate at three.
From classic localities to lesser-known sources, we work with suppliers around the world to find material that is genuinely what it is called. Locality is named on every quote, not the continent.
Gemmology, origins, sourcing and the grading vocabulary the trade actually uses.
Price per carat in 2026, by colour grade and size — with the numbers the trade quotes.
