    I got a really good price for my diamond ring. Joseph was extremely helpful in giving me the best deal I could get in comparison to other buyers in Hatton gardens. I highly recommend!

    Outstanding in every way. Joseph is honest/straightforward/knowledgeable/helpful and significantly better priced than competition. Buying a diamond was an absolute pleasure. Thank you!

    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.
