Membership tailored to your business
Membership of the London Diamond Bourse is selective and offered on an individual basis. Applicants are sponsored by existing members or supported by trade references, interviewed and vetted before admission, and every member trades under the rules of the Bourse and the World Federation of Diamond Bourses. Within that, the tiers are built around different working needs — from occasional use of a viewing room to a permanent desk on the floor.
Three ways to belong
All three carry the same standing, the same obligations and the same access to arbitration, governance and the member network. What differs is how much of the building you use, and whether you pay for it as you go or as part of your dues.
Affiliate
For professionals who want the standing and the network, and who use the premises occasionally rather than daily.
- Full member network, events and arbitration
- Use of the LDB logo and letterhead
- Calls taken on your behalf
- Trading floor, viewing rooms and equipment at day and hourly rates
Associate
For working dealers and makers who need the trade services — shipping, certification, directory presence — without a permanent desk.
- Everything in Affiliate
- Fast-track Kimberley Process certification
- Grouped shipping to GIA and De Beers
- Directory listing, WhatsApp trading groups and client reception
- Reduced rates on floor, rooms and equipment
Full Member
For those trading from Hatton Garden day to day, with the building and its facilities included rather than charged.
- Everything in Associate
- Trading floor and desk with diamond light, included
- Private viewing rooms, included
- Photography and diamond-testing equipment, included
- Registered post security service, included
Employee Membership
£3,475For the full-time employees of a Full Member, on a seat held and paid for by their employer.
- Liability accepted by the employer
- No capacity to trade on their own behalf
- No personal use of the LDB logo
- Acceptance subject to background checks
International Membership
£2,100For existing members of other WFDB bourses who trade in London periodically.
- Full membership with a hot desk, up to 20 days a year
- Additional days at the daily rate
- Open to WFDB members only

Benefits of being a member
Some of these protect you, some house you, some save you time. They are not equivalent, so they are not listed as though they were.

How admission works
There is a defined route in, and it is the same for every tier. Nothing here is designed to be difficult — it is designed so that every person on the floor can be vouched for.
Eligibility
- At least 21 years old
- At least one year working in the diamond and jewellery trade
- A UK registered company
- Current jewellery block insurance
Sponsorship
- Signed by two current members who know you personally, each a member for at least a year
- Council of Management members cannot sponsor
If you don't yet know a member: three references from recognised trade firms who have traded with you for three years or more — or two years on the LDB mentor programme.
The decision
- A membership interview
- Identity and credit reference checks
- A two-week holding period
- Acceptance by the Council, and entry in the Register of Members
Known to one another
Membership is offered on an individual basis, not to firms — and it is personal: every member is liable for their own obligations, including those undertaken through a company. Applicants are sponsored by two existing members, or supported by three trade references, and every member commits to the rules and ethical standards of the Bourse and of the World Federation of Diamond Bourses.
That is the whole basis of the floor — and the reason a transaction here can rest on a handshake and a word, backed by a body with the standing to enforce both.
Come and see the floor
The building answers most questions faster than a brochure does. We're glad to show you round and talk through which tier fits how you actually work.
