About

Not a Review Below Five Stars

Mouza work from Unit 4 at 99 Hatton Garden, crafting engagement rings and wedding bands around certified natural and lab-grown diamonds, with Miro the name that comes up again and again in the reviews. The house terms run deeper than most at this size: a lifetime warranty with lifetime cleaning, servicing and resizing, 30-day returns and a free valuation certificate.

Google shows 160 reviews. We analysed 150, and every one of them is five star, with 40 from the past twelve months. That puts them on our Highest Rated list, and they reply to 85 per cent of reviews.

The bespoke experience runs from an appointment through 3D rendered designs, refined until agreed, to a finished ring in around three to four weeks. Virtual appointments are offered for anyone who cannot get to the quarter, and the shop opens Sundays.

A hundred and fifty analysed reviews without one below five stars, and a lifetime warranty behind the ring.

What reviewers say

150Reviews analysed

150Five star

3Years of reviews

Depth of knowledge leads with 36 mentions, with 21 citing patience with questions and 18 the bespoke and design process. Thirteen reviewers describe being kept informed throughout, nine being guided through as a nervous first-timer, and eight that there was no pressure to buy, which earns places on our First-Time Buyers and No-Pressure Jewellers lists.

There is nothing below five stars to report, and 85 per cent of reviews get a reply. A young record, barely three years, but a spotless and well-tended one.

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.

Where to begin on my engagement ring journey with Mouza! I reached out to Miro with a relatively clear idea of (i) what I would like the end result to look like and (ii) what I felt was important for my now fiancé, both in terms of practical considerations and size/style.”

K Duffy · October 2023 · On Google

We bought our engagement ring and wedding band from Miro in November 23. We found his shop by chance whilst browsing in Hatton Garden. I was in between a few styles of rings at the time. Miro presented all possible options and always provided great suggestions based on what I liked about certain rings.”

Who this suits

The Right Buyer for Mouza

This suits a first-time buyer who wants to be walked through the decision: the guidance themes run right through the record, the process is staged with 3D renders before anything is made, and the lifetime warranty with free resizing takes the long-term worry out of sizing a surprise ring.

It also suits a weekend buyer, with Sunday opening, and anyone outside London, through virtual appointments. The shop is a unit inside 99 Hatton Garden, so book and head for the building entrance.
