London’s Most Reviewed
Engagement Ring Jewellers
Review volume is not the same as quality. But a jeweller with two thousand reviews has served a great many people, and a pattern that large is hard to fake. These twenty-five carry the most evidence in London, ordered by review count.
Volume brings its own bias: the biggest operations serve the most people, and a high-street window collects reviews faster than an appointment-only workshop. Read it as a measure of scale and track record rather than a quality ranking; the quality ranking is the Top 100, and the two orders disagree in instructive places.
The twenty-five largest review records across all 311 verified jewellers, ordered by review count. Ranked on the same Wilson score used for the Top 100, which weighs the proportion of positive reviews against how many stand behind it. Full method.

Gemima
Gemima is not in the ranking above, and cannot be: she has no Google Business Profile, so there is no review record to rank. She is here on judgement rather than data, which is why she sits apart from the seven.
The case for her is qualification. Gemima Macdonald is a GIA-qualified gemologist with a decade in the trade including time at Boodles, working appointment-only from a Hatton Garden workshop. She sources off-market, favours unconventional cuts, and runs a “Diamond & Design” appointment where you see stones side by side before committing. Commissions typically start around £5,000 over four to six weeks. Full profile.
