How does selling diamond jewellery for cash work?

Auction based valuations

When we offer valuations for those selling diamond jewellery in London, we base our valuation on several different aspects; however our valuations will take into account recent auction prices rather than insurance valuations. At Suttons and Robertsons, we buy diamonds and diamond jewellery from people on a pre-owned second-hand basis and value it accordingly. Insurance valuations are usually made on a New Replacement Value (NRV), which considers the cost of replacing the item from new.

How we value your diamond jewellery

These valuations are based on; the brand of jewellery (if any); the material used in the production of the pieces, from diamonds and other gemstones to precious metals; the condition that the jewellery is in, from pristine to used, and the provenance of the piece/s.

Provenance, or where jewellery has come from, is an important aspect of the valuation process. A certificate of sale and any other paperwork that records information about your jewellery adds value to our estimate. If you are selling diamond jewellery without a certificate, we are still able to offer you a valuation for the cash offer that we would make on your jewellery.

Where is the best place to sell diamond jewellery in London?

As London’s oldest pawnbrokers and jewellers, Suttons and Robertsons understand the importance of working quickly to get your valuation to you. Without compromising on customer service and a highly professional approach, we know that time is often of the essence. We’re in a position to work faster than an auction house or conventional jewellery brand and we can move from the point of valuation to placing the money in your bank account in as little as 24h. We also are happy to complete our purchase of your diamond jewellery in cash. In addition to our expert knowledge of diamond jewellery and its worth, we deliver a discrete but welcoming service.

Sell All Types of Diamond Jewellery to Us

At Suttons and Robertsons, we welcome the opportunity to view and offer valuations on diamond jewellery of all types. These include:

  • Diamond rings, from Tiffany engagement rings and DeBeers solitaire diamond rings to Boodles Full Eternity Rings
  • Necklaces, including the Cartier tennis necklace, and diamond chains
  • Earrings, such as Van Cleef and Arpels
  • Pendants and lockets, like Elsa Peretti for Tiffany and Co
  • Bangles and bracelets, including the Cartier Panthere bracelet

We also welcome more unusual diamond jewellery, including cufflinks, charms and brooches, including pieces that use the Van Cleef and Arpels Mystery setting.

Sell Your Certified and Uncertified Diamond Jewellery in London


Sell your GIA certified diamonds

We will be delighted to offer you a valuation for you GIA certified diamonds. It is important to be able to show us your certification as this can positively impact the valuation that we can offer you. Please feel free to bring them with you when you visit us in-store or you may also wish to email us a copy of your GIA certification.

Sell your diamond jewellery without a certificate

You may be wondering ‘can you sell diamond jewellery without a certificate?’ The short answer is yes. Selling diamond jewellery without a certificate may impact the valuation that we can give you but it won’t affect the sale of the jewellery or the speed at which we can get the money to you.
