Dazzle Diamonds London

Unit 12, Ground Floor, 99 Hatton Garden, EC1N 8NX · View on Google Maps · Visit website

Dazzle Diamonds London was set up in 2020 by M Muddassir A Jaleel and Muhammadu Shiham, who came to retail from international diamond and gemstone trading. The shop is Unit 12, on the ground floor of 99 Hatton Garden, and Jaleel is the name that comes up again and again in the reviews.

Google shows 549 reviews. We analysed 540: 534 are five star, four are four star, and two sit below that, in a record of almost six years. Seventy-seven arrived in the past twelve months.

The work is bespoke-led, with natural diamonds, lab-grown diamonds and coloured gemstones all on offer, and a five-stage design process set out on their site, from first conversation to finished piece.

Our Top 100 ranks every London business we could verify as a genuine engagement ring jeweller, 311 of them from a pool of 1,120 candidates, on the strength of their Google review evidence. Dazzle Diamonds London ranks #11 of 311.

They also appear on three of our ranked lists: No. 4 on our Open Sunday list and No. 9 on our Lab-Grown Specialists list, and they are on our Most Reviewed lists.

The bespoke and design process is the biggest theme, described by 64 reviewers. Forty-one mention depth of knowledge, 23 patience with questions, and 14 good value for the money. Eleven describe being guided through as a nervous first-timer, and ten say the ring came out better than they expected.

Two reviews sit below four stars. The detailed one describes a first mock-up that had to be redone before the ring was right. Against 534 five-star reviews that is a small share; agree the design details, including the metal, before making begins.

Review figures taken from Google and checked in September 2026. We recount them monthly.

This suits a buyer who wants the ring designed around a stone rather than picked from a window. Bespoke dominates the reviews, and the founders came from diamond and gemstone trading, so the conversation starts with the stone.

It also suits a weekend buyer. They open seven days, including Sunday 10.30am to 3.30pm, which puts them at No. 4 on our Open Sunday list, and they are No. 9 on our Lab-Grown Specialists list.

Visits are booked consultations rather than drop-ins, through their site or by phone. The shop is inside 99 Hatton Garden rather than behind a street window, so head for the building entrance and ask for Unit 12 on the ground floor.
