About us

Thank you for taking the time to visit our site. Knuckerbling are the top UK eBay seller of certificated diamond rings. We have more inventory than anyone else and sell at prices below internet diamond wholesalers.  As suppliers of diamonds to high-street jewellers, we are also happy to deal directly with the consumer:  the enormous mark-ups associated with the retail purchase of diamonds are thereby avoided.

Knuckerbling is the brainchild of Charles Bloomstein, who is the fourth generation of Bloomstein's bullion dealers. Charles's extensive knowledge of diamonds and precious metals has been gained during 20 years of experience within the firm.
It is the firm's old and established contacts, along with Charles's interest in technology that have made Knuckerbling one of the most trusted and successful precious jewellery sellers on eBay. We have now been trading on eBay since the year 2000.

We have fantastic connections in the jewellery and diamond trades. We buy our diamonds and products direct from site holders and jewellery factories, thereby cutting out wholesalers entirely. It is our aim to provide you with diamond jewellery at the lowest possible prices. All of our products, of which we are justifiably proud, are listed at a fraction of their retail prices.
We take commissions for bespoke jewellery. Our highly-trained staff will advise you throughout the process. In particular, they can offer advice on all aspects of diamonds (cut, colour, clarity, finish-grade and carat-weight), choice of metal, settings and design.

Our own jeweller is highly-skilled: he can replicate almost any design of your choice.

We continue to maintain our excellent standard of customer care at all points of sale - before, during, and after your purchase.
We subscribe to the old-fashioned way of doing business - politely, discreetly and individually.
Nothing less will do: you will receive exactly the same excellent quality of communication and customer care, whether you spend several thousand pounds - or nothing whatsoever! Just try us and see...

We maintain exceptionally high standards in all areas of our business.
For example:

  • We do not add VAT to final prices - we are VAT registered and VAT is included in the price
  • We do not charge re-stocking fees
  • We do not charge extortionately for fully-insured delivery - anywhere in the world
  • We do offer a 14 day no-quibble return option
  • We do support non-conflict diamonds
