About

Dimond Is the Surname, Antique Is the Trade

Dimond London is the Dimond family’s business at 100 Hatton Garden, and the spelling is the surname, not a typo. The trade is old stones done properly: antique, Art Deco and vintage engagement rings, ready-to-ship ranges organised under £5,000 and under £10,000, education pages on antique diamonds, and remodelling for pieces that deserve a second life.

Google shows 63 reviews, every one of them five star, in a record two years young with 29 from the past twelve months, and they reply to about half.

The review themes are strong for a young listing: knowledge and the bespoke process lead jointly, with seven reviewers describing being guided through as nervous first-timers.

A family surname over the door and antique diamonds inside, with the stock priced into honest brackets.

2Years of reviews

Depth of knowledge and the bespoke and design process lead jointly with 14 mentions each, with eight reviewers saying the partner loves the ring, seven being guided as first-timers and five that the ring exceeded expectations.

Nothing sits below five stars, and around half the reviews carry a reply. A young record reading very well.

For scale: that record sits in the top 1 per cent for the share of reviews at four stars or better. In plain terms, you should be in safe hands here.

I had an incredible experience with Dimond London, thanks to Harry’s expertise and care throughout the process of creating my bespoke engagement ring. From the start, Harry made me feel completely at ease, there was no pressure, and he ensured the diamond choice was entirely mine.”
Matthew Cole · November 2024 · On Google
Buying an engagement ring is such a huge moment and one that can feel quite daunting! I am so incredibly happy and thankful to Harry for making the experience so smooth and enjoyable. If I could add stars to this review I would! I had the most amazing experience from my initial meeting all the way through to collecting my ring.”
