London Engagement Ring Jewellers
You Can Walk Into
Most of London’s best rated engagement ring jewellers work by appointment, and turning up unannounced is the single most common way a first visit gets wasted. These seven do not require one. Each states walk-ins are welcome on its own Google listing.
114 of the 311 verified jewellers state that walk-ins are welcome. The seven below are the highest rated of them. 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.
