We Buy Rough uncut stones, bought at source

We buy emerald rough.

Almost always included — 'jardin' is expected and is not a defect in the way it would be in sapphire.

Send photographs of what you have Tell us the weight and where it is from. There is no obligation.

How to tell if this is what you have

Crystal habit

Hexagonal prisms, commonly flat-terminated and still in matrix. Colombian material often in calcite or black shale.

Crystal system

hexagonal

As rough

Almost always included — 'jardin' is expected and is not a defect in the way it would be in sapphire.

What it gets mistaken for

Emerald is commonly confused with green tourmaline, tsavorite, green fluorite and doublets. That cuts both ways — people sell it as something less than it is at least as often as the reverse. If you are not certain what you have, send photographs anyway and say you are not sure. We would far rather look at something and tell you it is not what you hoped than have you throw it back on the heap.

Where it comes from

We buy emerald from Colombia, Zambia, Brazil, Ethiopia, Afghanistan, Madagascar, Russia — and from anywhere else it turns up. A locality we have not listed is an omission, not a refusal.

Treatment

OILING IS NEAR-UNIVERSAL and disclosed by degree. Resin and polymer filling is a different matter.

Tell us what has been done to it, if you know. We buy treated material where the treatment is a normal part of the trade — what we cannot do is find out afterwards, because then it is a problem for whoever owns the stone next and eventually that is us.

How to photograph it

Daylight, on a plain white surface, and wet and dry both. Rough seen dry is frosted and reads far paler and greyer than the same stone wet — a parcel photographed dry has cost its owner money more times than we can count. Put a coin or a ruler in the frame for scale. The full guide is here.
