I designed and bought a beautiful bespoke engagement ring with Leiser & Co. They made it a thoroughly enjoyable experience. The ring came out exactly as I was hoping for, the craftsmanship and diamond quality are great. Most importantly… She said yes!

Recently met with Olivier from Leiser & Co to sell a diamond ring. Price was super and service excellent. Can definitely recommend.

Very professional service and Olivier was very helpful. Fair price for rings given. Definitely recommend.

Elite service - went to get a quote on an engagement ring, and was so pleased with the quality and price of the diamonds I saw that I ended up buying the perfect diamond and designed my engagement ring that day. Highly recommend, but know what you want when you go in there so they can show you the best options. Thank you Olivier!

I am writing this review to say a huge thank you for all your help and support in selling my diamond. I couldn’t recommend this company more highly. They were professional, informative and efficient every step of the way and kept me informed throughout. I would definitely use them again for their sound knowledge and competitive prices. Many thanks for a fantastic service!! Aline

What can I say...I am extremely satisfied with my experience with Leiser & Co. - not only did I find the best price for a diamond in Hatton Garden, I was thoroughly impressed by the personable service and level of professionalism of the dealers.

Had some diamond jewellery that I wanted to sell and went to a few places on Hatton Garden. Ended up selling at Leiser & Co as the offered me the best price. Nice and friendly service too!

I had a very specific bracelet in mind that I wanted and looked everywhere. The price at Leiser and Co was not only competitive, the quality of the diamonds were also far superior to what I had seen for the price. Very happy!
