Flawless Fine Jewellery

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

Flawless Fine Jewellery trade from 107 Hatton Garden with one of the largest review records on this site. Google shows 2,260 reviews; we analysed 2,180 of them and found 2,160 five star, with 12 critical reviews across seven years. That works out at a 99.4 per cent four-and-five-star rate at a volume where most records fray.

The scale is current, with 704 reviews arriving in the past year. Their Google listing carries a wider trade set than most, spanning diamond dealer, gemologist, goldsmith, manufacturer and wholesaler, and they sell both lab-grown and what their own navigation calls earth-mined diamonds side by side.

They reply to 22 per cent of reviews, including the critical ones, so you can see how complaints were handled.

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. Flawless Fine Jewellery rank #6 of 311.

They also hold No. 2 on our Most Reviewed list, No. 2 on our Open Sunday list, No. 4 on our First-Time Buyers list, No. 4 on our Lab-Grown Specialists list, and No. 6 on our No-Pressure list.

At this volume every theme is heavily populated. 297 reviewers mention depth of knowledge, 205 describe patient question-handling, and 100 talk through the bespoke and design process. Sixty-nine mention no pressure to buy, 62 mention aftercare and resizing, and 60 describe being guided through as nervous first-timers, one of the strongest first-timer counts we recorded.

The criticism is small but has a shape: among the 12 critical reviews, the recurring topics are delays, communication going quiet, and reception on arrival. At 12 in 2,180 that is a low failure rate, and the same two failure modes recur across the whole quarter, but it is worth getting your dates and your point of contact in writing.

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

This suits a first-time buyer who wants the odds on their side: 60 reviewers describe being walked through as beginners and 205 describe having their questions answered without hurry, on a sample large enough to mean something.

It also suits anyone comparing natural against lab-grown in one sitting, since both ranges sit in the same shop, and Sunday shoppers, with the shop open seven days.

Is Flawless Fine Jewellery open on Sundays?

Yes, 11am to 3.30pm, alongside 10am to 5.30pm Monday to Saturday. They are No. 2 on our Sunday-opening list.

Do they sell lab-grown diamonds?

Yes, both. Their own navigation separates lab-grown diamonds from earth-mined diamonds, so you can compare the two ranges in one shop.

What is their review record like?

Google shows 2,260 reviews. We analysed 2,180: 2,160 five star and 12 critical, a 99.4 per cent positive rate over seven years, with 704 reviews in the past year.

Why are they ranked #6 of 311?

The ranking is built on Google review evidence across every London jeweller we could verify as a genuine engagement ring business. Very few records combine this volume with this consistency.
