How We Work
Mayfair Diamonds is a diamond and precious stones brokerage that sources diamonds for clients at wholesale prices, commissions jewellery to be made and sells jewellery on behalf of clients on a commission basis. We work on your behalf to source what you want, rather than selling from stock, so you really can get what you want. We source from a very wide market of suppliers – the same suppliers that shops use, but you get the price they pay. Because we work with wholesale diamond suppliers in the UK and internationally, we can source diamonds, precious stones and jewellery up to 65% cheaper than the price you would pay in a high street shop.

Our service is unique; we source the same high quality certificated stones as offered by Mayfair & Knightsbridge Retailers but at a discount of up to 65% from the shop prices.. It is our contacts and sourcing of the stones that allows you to access this very private market. You are able to inspect the diamonds in person rather than online, giving you assurance of their quality and provenance. We invoice you separately for our commission. All of our diamonds are GIA Certificated and guaranteed non-conflict on the invoice so that you are able to insure them without any issues. We are a trusted and highly recommended brokerage and we generate most of our businesses by referrals from previous clients and recommendations. We thrive on trust and with our unique structure, where we work on your behalf to negotiate the best rate, you have the confidence of knowing that we are working only for you.
We can sell your jewellery
With our private collector and international trade connections, we are perfectly placed to sell jewellery that you no longer wish to own at the best possible price. We can value and dispose of family collections, estate assets and personal jewellery, often achieving higher prices than auctions.

We are Expert Valuers
With more than 30 years experience at the highest levels of the international jewellery and auction trade, we are expert valuers for fine jewellery whether antique or modern for insurance, probate, family division, disposal of assets and expert consultancy. We also regularly act as expert witnesses in civil, criminal and family courts.

Empowering customers through education
Over the years we have given lectures and private classes introducing buyers to ‘The Four Cs’ (Colour, Clarity, Cut and Carat) and other aspects of jewellery valuing. Our aim has always been to spread understanding of what diamonds and precious stones are, how they are categorised and valued so that we give our customer enough knowledge to know what they are buying, why, and when to say yes or no. We are your confidential adviser, there to give you confidence when buying, selling or commissioning.
