I would highly recommend Jonathan. He is very professional, courteous, and very knowledgeable. Jonathan helped source a diamond and also assisted with the design process. He went out of his way to meet me on a number of occasions to ensure I found the diamond I was looking for.

Jonathan’s services were recommended to me as I looked for a special piece to recognise a “significant” birthday. What a gentleman to deal with! Jonathan was invaluable in advising me, ensuring I’ve ended up with something completely spectacular. I cannot recommend Jonathan more highly.

Jonathan is a very professional antique jewellery finder. His knowledge of diamonds and precious stones is second to none. He sourced a very unique piece of jewellery for me and has very good contacts regarding setting and designing specialist pieces. He keeps you informed and updated regarding dealings with clients during the sales process and works very hard at gaining the most favourable price . I highly recommend his services.

Happy to recommend Jonty as a safe pair of hands who can ably guide any new buyer through the process of sourcing the perfect stone, and create an exquisite ring with an end result exceeding all expectations, and going the extra mile at every point along the way to deliver the highest level of service.

I have nothing but positive words to say about Jonty & Mayfair Diamonds. The entire process was very smooth and Jonty is a very personable and approachable character and clearly very knowledgable in his field. I am 100% convinced that having used Jontys Services as well as his recommended Jeweller – I could not possibly have achieved a better finished result.

From start to finish Jonty has been an absolute pleasure. We was very specific with our brief and knew what we wanted for our special day would indeed be a challenge. We had spent months using different recommendations and continued to hit brick walls and facing the reality we would have to settle for second best.That was until we met with Jonty at Mayfair Diamonds. I Would highly recommend Jonty and his amazing expertise and incredible sourcing skills, and have already set him the task of sourcing other treasures.

Jonty possesses a confidence-inspiring combination of deep expertise, an easy manner and total commitment to ensuring his clients get what they want at a highly reasonable cost. He came recommended to us by a friend who had worked with him at Sotheby’s. We required a valuation and the resetting of an heirloom gem — a small project for him — but the quality of his advice and work were excellent.
