We Sell

The same stone, without the shop window attached to the price

Acquisition by brief, from the trading floor rather than the retail counter. You see what we see, you pay close to what we pay, and nothing is bought on paper alone.

A diamond in a boutique window has travelled a long way from the cutter, and every stop has added a margin. The stone itself may be excellent. What you are also paying for is the lease on the street it sits on, the staff who showed it to you, the inventory that has not sold, and the brand’s advertising for the year.

We start from the other end. You tell us what the piece is for and what actually matters to you — and, just as usefully, what does not. We then search the market we trade in every day, and present a shortlist with the reasoning attached: this one has superb light return but a feather near the girdle; this one is a grade lower on colour but eleven percent cheaper and will look identical once set in rose gold.

Nothing is ever sold on paper. Certificates describe a stone; they do not show you how it behaves. We put the shortlist on a tray in front of you, under both daylight-equivalent and warm lighting, and let the stones argue their own case. It is remarkable how often the one that wins is not the one with the best report.

What we source

Sourced to a brief, not held in stock

Certified diamonds

GIA-certified stones in every shape from 0.50ct to 30ct and beyond, including triple-excellent round brilliants, elongated fancy shapes and matched pairs.

Investment-grade stones

D-flawless rounds, fancy vivid coloured diamonds and top-colour large goods, selected for scarcity and liquidity rather than for appearance alone.

Rare coloured gemstones

Unheated Burmese ruby, Kashmir and Ceylon sapphire, Colombian emerald, Paraíba tourmaline — with GÜBELIN, SSEF or AGL reports confirming origin and treatment.

Signed & period jewellery

Archive and discontinued pieces by Cartier, Van Cleef & Arpels, Bulgari and Boucheron, located through dealer and auction channels not open to the public.

Collectible watches

Specific references sourced to order — Patek, Rolex, AP, Richard Mille, Lange — with honest commentary on condition, originality and what the market is actually paying.

Bespoke commissions

Stone first, then design. We source the centre stone, then work with Dubai and Geneva workshops to build the piece around it, with CAD approval at every stage.

On the tray

It is remarkable how often the winner is not the one with the best report.

Certificates describe a stone. They do not show you how it behaves. Every shortlist is laid out under both daylight-equivalent and warm light, and the stones argue their own case.

The process

Four stages, one conversation at a time

  1. I

    The brief

    A conversation, not a form. What the piece is for, the parameters that genuinely matter to you, the ones that do not, and the budget you are working within. Half an hour here saves weeks later.

  2. II

    The search

    We work our network — Antwerp, Mumbai, Geneva, New York — for stones and pieces matching the brief. You receive a shortlist with full certification, honest commentary and a price for each.

  3. III

    Inspection

    Nothing is bought on paper. Shortlisted stones are brought to Dubai, or to you, so you can see them side by side under proper lighting before any commitment.

  4. IV

    Acquisition & setting

    We acquire at trade level and, if you wish, commission the setting with workshops we have used for decades. You receive the certificate, the invoice and an independent valuation for insurance.

Questions

Buying through us

How much cheaper is buying at trade level?

For the same stone with the same certificate, typically twenty-five to forty percent below luxury boutique retail, and meaningfully below most independent jewellers. The saving is structural rather than promotional: there is no showroom, no seasonal collection, no display inventory to finance, no sales commission and no marketing budget. You are paying for the stone, our margin and the setting, and that is all.

Can I see the diamond before committing?

Always, and we would decline to sell on any other basis. Certificates describe a stone; they do not show you how it behaves in light. We bring shortlisted stones to Dubai, or to you, and lay them out side by side under both daylight-equivalent and warm lighting. Differences that are invisible on paper become obvious in thirty seconds on a tray.

Do you provide a valuation for insurance?

Yes. Every acquisition is accompanied by the laboratory certificate, a detailed invoice and an independent insurance valuation at replacement value — which is deliberately higher than what you paid, because that is what replacement in the retail market would actually cost. Insurers require this, and we prepare it as standard rather than as an extra.

Will you buy the piece back later?

Yes, and we say so in writing at the point of sale. Because you acquired at trade level rather than retail, the gap between what you paid and what we can pay on a future purchase is far narrower than it would be on a boutique piece. We cannot promise a price years in advance — no honest dealer can — but we can promise that you will be quoted against the same international benchmarks we use for every other seller.
