    Our Process

    How to Sell A Diamond Ring Or Diamond Jewellery With YL Diamonds

    OPTION 1


    When selling a diamond or piece of jewellery, we like to see it in person so that we can analyse it and give you the highest price possible based on the item’s particular specifications. Small variations can result in significant pricing differences. We operate by appointment only so please call ahead to make an appointment.

    One of our diamond valuers will examine your diamond to ensure it matches the certification (if it is certified) and to assess any imperfections. We’ll need you to complete a declaration of sale document and supply us with photographic identification, such as a driver’s licence or passport, once we’ve agreed on a price. We will pay you on the spot, and the money will reach your account instantly.

    OPTION 2


    If you cannot visit us, you can request an estimate for your diamond by providing as much information as possible. Please bear in mind that online jewellery valuations are not offers to buy, and we will make a final offer once we see the item in person. The more information you supply, the more accurate our estimate will be.


    After the initial valuation, I complete and you are happy to proceed, we will arrange to send you a secure delivery bag for you to ship your jewellery to us via a fully insured and tracked UK delivery service free of charge.


    After we have received your package, one of our experts will assess your diamond in person and will offer you a final valuation. If you accept our offer we guarantee to pay you within an hour. If decide not to go ahead then we will send your item back via express mail.

    A fantastic experience at YL Diamonds. From initial communication to agreeing a price, Joseph was very amenable and patient. He took the time to speak to me and my partner about how prices were reached and why. This was done in a very unhurried way. He offered a higher price than competitors and there was no pressure. He was also happy to offer advice on some other items I decided not to sell in terms of how to get the best price. I would highly recommend YL Diamonds to anyone looking to sell their jewellery. Thank you so much for such an open and easy transaction.
