Why join

Why become a member?

Membership offers more than a professional address. What an office cannot provide is a room where every person in it has been vetted, a word carries a penalty if it is broken, and the equipment on the table would cost a small firm a year’s profit to buy alone.

The London Diamond Bourse is the United Kingdom’s only diamond, gemstone and jewellery trading floor. It has been on this street since 1940. Discover the benefits of membership.

The trading floor at the London Diamond Bourse

Purpose-designed trading facilities

The Bourse is not an office with a lock on the door. Entry is controlled, every visitor is signed in, and every member in the building has been vetted before admission. The Bourse provides controlled access and facilities designed for professional diamond and jewellery trading.

Secure premises, secure letter storage and a registered post security service, with discounted UltraVault safety deposit for members who need it.

Every applicant is vetted before admission — references, interview and checks — and every member trades under the rules of the Bourse.

A connected professional community

Dealers, cutters, setters, valuers, gemmologists, manufacturers, retailers and insurers — the trade is not one job, and a working day often needs three or four of them. Most of our members are in the building or a few minutes’ walk from it.

Members are listed in the online directory, carry the LDB name, and reach each other through member events, trading groups and the floor itself.

Our members’ directory lists the firms publicly, searchable by specialism — from rough and melee to valuation, watches and insurance.

Inside the London Diamond Bourse at 100 Hatton Garden

A word, backed by a body that can enforce it

Diamonds have always moved faster than contracts. A deal on this floor can rest on a handshake and the phrase mazal u’bracha, and both sides know what that costs if it is broken.

That works because the Bourse arbitrates — between members, and between members and non-members — under its own rules and bye-laws and the standards of the World Federation of Diamond Bourses. It is the difference between trusting a person and trusting a system.

Arbitration and dispute resolution, under the rules of the LDB and the WFDB, is available to every member.

Synthetic-diamond detection equipment at the Bourse

Equipment most firms could not justify alone

Trading floor desks with diamond lights. Private viewing rooms for clients and stones. A boardroom and meeting space. Photography equipment and synthetic-diamond detection. A client reception area with desks, scales and lights.

Bought individually, this is capital a small firm cannot easily release. Shared across the membership, it is simply what the building has.

Included at Full Member level; available to Affiliate and Associate members at day and hourly rates.

Where the trade teaches the trade

CPD-accredited courses in diamonds, in manufacturing and in coloured gemstones, taught by people who deal in them rather than only write about them. Seminars and member events through the year.

For those earlier in their careers, the mentor programme pairs newer entrants with established members — the way this trade has always passed knowledge down.

Courses are open to members and to the wider trade, with member rates. See the courses.

100 Hatton Garden

The address does work that marketing cannot. Hatton Garden has been the centre of the British trade since the nineteenth century, and clients, insurers and overseas buyers read it that way without being told.

The Bourse has been part of that street’s working life since 1940, and is the United Kingdom’s only diamond, gemstone and jewellery trading floor.

Central London, on the street the trade already comes to.

Recognised beyond this building

The London Diamond Bourse is a member of the World Federation of Diamond Bourses — one of around thirty bourses across twenty-two countries — which means a member here is known in Antwerp, Tel Aviv, Mumbai and New York.

The Bourse is recognised by the Foreign, Commonwealth & Development Office as a trade association, represents the trade to government, and fast-tracks Kimberley Process certification with the Government Diamond Office.

Membership here is standing abroad, not only in London.

Come and look first

Most people join after they have stood on the floor. There is no obligation in any of these, and the first two are the ones we would suggest.
