Diamour Jewellers

109 Hatton Garden, EC1N 8LY · View on Google Maps · Visit website

Diamour Jewellers trade from 109 Hatton Garden and rank #5 of the 311 London jewellers we verified. The record is young and dense: Google shows 489 reviews, we analysed 480 of them, and the split is 478 five star, two four star, and nothing below. More than half of it, 286 reviews, arrived in the past year.

They sell both natural and lab-grown, and their site is built around that choice: the engagement ring menu starts with either a natural diamond or a lab diamond and works forward from the stone. They reply to 55 per cent of reviews.

The opening hours are a practical advantage. Seven days a week, to 6.30pm Monday to Saturday, which is why they sit at No. 1 on our Sunday-opening list and No. 3 for late opening.

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. Diamour Jewellers rank #5 of 311.

They also hold No. 1 on our Open Sunday list, No. 3 on our Open Late list, No. 3 on our Lab-Grown Specialists list, No. 4 on our Highest Rated list, and No. 5 on our No-Pressure list.

Depth of knowledge is the leading theme with 40 mentions, and 20 reviewers describe being given patient time with their questions. Eleven talk through the bespoke and design process, and eight mention good value for the money.

Five reviewers mention speed of turnaround and five describe arriving as complete beginners. The record has no critical reviews to weigh: nothing below four stars in the 480 we analysed.

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

This suits a buyer whose ring shopping has to happen on a Sunday or after work. Diamour's seven-day week and 6.30pm closes are why they hold the No. 1 spot on our Sunday list and No. 3 for late opening.

It also suits a buyer who wants natural and lab-grown priced side by side. Their range is organised around that comparison from the first click, so the decision stays yours.

The record is shorter than the street's veterans, at under two years of history, so treat it as a very strong current form rather than a long institutional one.

Is Diamour Jewellers open on Sundays?

Do they sell lab-grown diamonds?

Yes, both. Their engagement ring range starts from either a natural diamond or a lab-grown one, so you can compare the two directly.

Why are they ranked #5 of 311?
