Rapid 24-Hour Quotes Get an expert valuation delivered straight to your inbox within one business day of your request.
We buy a wide range of jewellery, including antique, vintage and modern pieces. This includes rings, necklaces, bracelets, earrings and brooches. We're interested in items made from precious metals like gold, platinum and silver, especially those with diamonds or other gemstones
The value of jewellery is determined by several factors, including the type and weight of the metal, the quality and size of any diamonds or gemstones, the designer or brand and the overall condition of the piece. Our expert appraisers will evaluate your item to provide you with an accurate and fair offer.
No problem. While a certificate (like a GIA report) is helpful, it's not required. We have certified gemologists who can accurately grade your diamond and determine it's value.
We still buy damaged or broken jewellery. The value is primarily in the precious metals and stones, which we can salvage. We'll assess the piece and make an offer based on the value of its components.
Our process is transparent and straightforward. First, you'll bring or send your item in for an evaluation. Our specialists will then carefully examine your jewellery, testing the metal and assessing any stones. We'll explain the factors that contribute to its value and present you with a no-obligation offer. Most appraisals are completed in a short amount of time, often while you wait. For more complex collections, it might take a bit longer, but we'll keep you informed throughout the process.

"Excellent Service Provided"
After my divorce, I didn't want to keep my engagement and wedding rings any more. Daniel arranged for these to be collected and was quickly able to offer a fair price for them.
I was very happy.
Nicola Goodrich
"Happy to Receive my Money"
I'd been meaning to sell a watch I no longer wear and finally got in touch with 4Cs. I was surprised how easy everything was. I visited them in London for assessment, then quickly received a quote and my payment.
"Amazing Service"
I inherited some fancy jewellery from my Aunt - but it wasn't my style. I sold it all via 4Cs Diamonds and have bought something much more modern that I am enjoying wearing.
