Buying & Selling Diamonds in London

Our expertise in the diamond market and appraisals allows us to offer our clients extremely competitive prices when they buy diamonds.

Our large turnover and many business contacts allows us to find the proper buyer for you at the right price. For this reason, you can sell your diamonds with confidence that you will receive the best possible payout for goods.

Experts in Certified Diamonds

We specialise in certified diamonds by the most trusted diamond grading companies in the world. Some of them for example include: GIA, HRD and IGI.

We are also GIA-certified graders with three generations of experience, but we work with diamonds that do not have certificates as well.

Free Appraisals

We will gladly offer free appraisals for any of the diamonds you might bring into our London office.

Please note however that this is only done by appointment.

Custom Jewellery

We work with casters, goldsmiths and designers directly, and are able to create any custom model you might come up with. If you would like to get a quote for a price on a custom item of jewellery, please don't hesitate to contact us, whether it is men's rings, engagement rings, necklaces, pendants, bracelets or anything else.
