A Colombian emerald, a period ring or a loose stone: the house examines and buys emeralds at international market prices, by appointment in Paris at 22 rue Drouot or in London at 100 Hatton Garden.
The emerald is the subtlest of coloured stones: its origin (Colombia, Zambia, Brazil), its intensity and its degree of oiling determine its value. The house, dealer and diamond merchant, member of the Syndicat des Négociants en Art (SNA), buys emeralds of every size and every provenance — from Muzo to Zambia —, mounted or loose, with or without a report from SSEF, Gübelin, GRS, AGL, GIA or LFG. The stone is examined in front of you by Ariel Altmann, a gemmologist by training, and never leaves your sight; a small Muzo emerald of deep green can be worth more than a large pale stone.
Complimentary first opinion on photographs, firm offer, same-day payment.

To 22 rue Drouot in Paris or 100 Hatton Garden in London, by appointment. The piece is examined in front of you; the firm offer is made on the piece itself, and payment follows agreement, the same day.

We look at these six points in front of you, then we make a firm offer.
An intense, vivid green, neither too dark nor too pale: the colour decides first, whatever the provenance.
Almost all emeralds are oiled. Minor oil sells well, a stone without oil is rare; heavy resin filling weighs on the offer.
Inclusions — the “jardin” — are natural; they count when they weaken the stone or darken it.
Emerald cut, cushion, cabochon, old cut: weight, proportions and the state of the edges are examined — the emerald fears knocks.
Colombia, Zambia, Brazil, Afghanistan, Ethiopia… The origin adds value without deciding everything.
A report from SSEF, Gübelin, GRS, AGL, GIA or LFG, a period or signed mount, add to the piece. Without papers, we examine all the same: the stone speaks first.
Many emeralds arrive with their certificate: we read it with you, then we look at the stone.
The reports most often brought to us, from the great Swiss and American laboratories to the Laboratoire Français de Gemmologie in Paris: we read them all, with you.
The nature of the stone — natural or synthetic emerald —, its weight, its dimensions, its shape, its colour.
The degree of oil or resin — none, minor, moderate or more — is the mention that weighs most.
Colombia, Zambia, Brazil, Afghanistan…: the report's opinion of origin counts in the price, without deciding everything.
For an important stone, a recent report reassures the buyer; we will tell you whether the one you have is enough.
We check that the report matches your emerald — weight, dimensions. An old report keeps its value; we will tell you whether an update is worthwhile.
The origin (Colombia first), the colour, the transparency, the weight and the degree of treatment (oiling). A certified “no oil” emerald can be worth several times the price of an equivalent oiled stone.
It is valuable for establishing origin and treatment, but not compulsory: we examine the stone on the spot.
Yes, mounted or loose, singly or in parcels.
To a dealer who buys these stones himself and can make you a firm offer. The house examines your emerald in front of you, tells you what it is and what it is worth on the market, and then you decide. Compare if you wish: we encourage it.
Yes. A Muzo emerald of a carat or less, of deep green and lightly oiled, can be worth far more than a large pale stone. It is the colour that makes the price.
Yes, with or without a certificate. These stones are shown by appointment, in complete discretion, in Paris or in London; the emerald never leaves your sight, the offer is firm and payment follows agreement, the same day, whatever the amount.
Often, quality for quality: Muzo and Chivor made the stone's reputation. But a fine Zambian or Brazilian emerald sells too: we buy from every provenance.
Yes: that is the case of almost every emerald. We look at the degree of oil and the state of the stone, and tell you frankly.
It is possible in a jewel made after the 1930s, when synthetic emeralds appeared. The mount then keeps its value, and we tell you frankly.
Yes. The house receives in London by appointment at its office, 100 Hatton Garden, EC1N 8NX, in the jewellery quarter. Write first by WhatsApp or e-mail with photographs; the appointment is fixed around the house's visits.
Yes. Once agreement is reached, payment is made the same day, by bank transfer, whatever the amount — with no fees or commission.
Verifiable facts, reviewed in October 2026. For a specific case, the appointment settles the matter.
The Spaniards seized the Colombian mines, worked before them — Chivor, then Muzo; their emeralds reached Europe, then Mughal India.
Art Deco brought back the carved emeralds of India, mixed with rubies and sapphires.
The first synthetic emeralds appeared; Carroll Chatham sold his in the 1940s. Since then, an emerald in a more recent jewel may not be natural.
Complimentary and confidential first opinion within 24 hours; then an appointment in Paris or London.
