How to sell your diamonds

We offer a great way to sell diamonds, without any of the hassle or haggling. Just pop them in the post to us, using our fast, free and secure service.

Once we have received your diamonds, we'll appraise them and let you know what the value is. If you want to accept our price we'll give you cash instantly, if not, we'll return your diamonds for free.

Diamonds are the hardest material on Earth. They have been a much sought after and admired gemstone for thousands of years.

Diamonds are found and mined in many countries all over the world. Worldwide deposits are estimated to be some 1.2 billion carats, with Russia boasting the largest reserve.

The Pink Star is the most expensive diamond ever sold. It is a 59.60 carat vivid pink fancy diamond that sold for £54.1 million in 2018. It was first sold at auction in 2013, for £63.1 million, but the buyer defaulted on the deal, so it came back up for auction.

We can't guarantee that you will be able to sell your diamond for quite so much. But we always buy diamonds at a fair price based on current market values.

The demand for second hand diamond jewellery is not always strong, so it can have lower resale value. This can be particularly upsetting if you remember how much you bought your diamonds for.

Diamonds, like cars, often depreciate in value as soon as you've purchased them. That's why we buy diamonds with a free appraisal and free returns service.

We'll even tell you if we think you can sell your diamonds for more money elsewhere. Make a start today, there's nothing to lose and cash to gain.
