You can sell costume jewellery through marketplaces such as eBay and Vinted, as well as some auction houses, jewellers and antique buyers. Unfortunately, we do not buy costume jewellery.

Yes, some diamond buyers purchase loose stones. However, we do not buy loose diamonds.

We buy many types of rings, including diamond rings, engagement rings, solitaire rings, eternity rings, cocktail rings, sapphire rings, ruby rings and emerald rings. Their resale value can vary depending on current trends, gemstone grading, certification, the grading laboratory, whether they are designer pieces and the precious metal used, usually platinum or gold.

The most popular diamond shapes we see selling quickly on the resale market include round brilliant, princess, emerald, oval, cushion and marquise cuts.

Rings in small sizes can be difficult to resell, so on occasion we may not be able to help. Larger rings can often be resized, but if resizing is not possible, this may affect their resale value.

Please note, our minimum natural diamond carat size is 0.70ct.

Jewellery from designer brands such as Cartier, Tiffany & Co. and Van Cleef & Arpels tends to retain the most resale value. In many cases, this is between 60% and 90% of the original retail price. Iconic collections such as Cartier Love and Juste un Clou, Tiffany T and Van Cleef & Arpels Alhambra are currently very popular on the second hand jewellery market. Pieces in excellent condition with their original packaging and certificates typically command the highest resale prices.

The resale value of unbranded platinum and gold jewellery often depends on whether the pieces can be resold or are valued based on their precious metal weight and purity. If the valuation is based on precious metal value, live market prices will significantly influence the price you receive. Precious metal prices increased considerably during 2025 and 2026, so you will receive a higher percentage of the original retail value now.

We do not buy antique jewellery, but we do buy vintage jewellery. Antique jewellery is generally at least 100 years old, while vintage jewellery is usually between 20 and 100 years old. If you are unsure, please get in touch and we can assess your jewellery online first.

We are online and London jewellery buyers who purchase used diamond earrings, including studs, drop earrings and diamond hoops. Our diamond earring valuations are based on their resale value, and not the scrap value.

You can sell second hand jewellery in several ways. The best option depends on its resale value and how much time and effort you want to spend:

• Luxury pawnbrokers and jewellers – We offer same day payment and cash for jewellery, especially jewellery made from gold, platinum, or featuring quality diamonds or branded designs. Ideal for jewellery with a resale value between £1,000 to £50,000.
• Auction houses – Auction houses are ideal for selling jewellery with a high resale value of more than £50,000 as they attract a different clientel, though it can take longer to sell and there are seller fees of between 10 and 25%.
• Online jewellery selling platforms – Examples are websites like eBay and Vinted, but these involve more effort, fees, and some risk. Suited to jewellery with a resale value of less than £1,000.

If you are looking for a quick and secure sale, our experienced jewellery buyers can help.

We are one of the best places to sell unwanted diamond jewellery for cash. We buy diamond jewellery of all types. These could include diamond rings, earrings, pendants, bracelets and more. We also welcome more unusual diamond jewellery, including charms and brooches, especially designer jewellery with high resale values.

First, decide between an outright sale and a consignment sale. For an outright sale, choose a reputable jeweller or jewellery buyer that provides fair valuations, has a convenient physical store or insured courier service, and makes payments quickly. Be ready to provide clear photographs, a diamond grading report such as a GIA certificate, and the original purchase receipt.

There are many different types of jewellery valuations. However, the most appropriate valuations for selling jewellery for cash are:

1. Resale valuation - This is the amount your diamond jewellery is expected to sell for before the costs of selling have been deducted. Typically, for natural diamond jewellery this would be 30% to 50% of the original purchase price and for designer jewellery such as Cartier, it can be up to 90%.
   
2. Cash valuation - While the jewellery resale valuation is what your jewellery is worth, if you are selling jewellery to a jeweller like us, you will receive less than that because we are jewellery buyers who will sell your piece on to a new buyer for a small profit.
3. Insurance valuation - This type of valuation provides the estimated retail replacement value of an item. It is typically higher than resale prices and is used for insuring your jewellery against loss, damage or theft, rather than for resale. Clients often refer to the jewellery insurance valuation, though unfortunately it is not realistic to receive this on the secondary market.

In most cases, we do not buy silver jewellery. We are primarily gold and platinum jewellery buyers, as silver typically has a lower resale value. If your silver jewellery is valued at over £500, there is a possibility we make be interested in buying it. Please get in touch to find out.

No, unfortunately, we don’t buy and sell lab grown diamond jewellery, as the resale value is generally between 10% and 30% of the original retail price, which is lower than natural diamond jewellery. While lab grown diamonds are visually identical, they don’t hold value in the same way on the second hand jewellery market.

Yes, we buy GIA-certified diamond jewellery in London and online. Please include a photo of the GIA certificate with your enquiry and provide the original certificate when you sell your diamond. GIA-certified diamond jewellery generally has a higher resale value than jewellery with certificates from other laboratories due to GIA’s reputation and the reliability of its grading.

The short answer is yes. You can sell uncertified diamond jewellery to a jeweller and pawnbroker like us, although not having a certificate may affect the valuation. In some cases, we may be unable to buy 2nd hand jewellery without one.

Yes, you can sell a diamond tennis bracelet to us in central London. They are often desirable on the 2nd hand jewellery market, particularly if they feature good quality diamonds and craftsmanship.
