London Engagement Ring Jewellers
Open on a Sunday
More of the trade opens on a Sunday than most people expect, though usually on shorter hours, with late starts and mid-afternoon closes. These are the best rated of them, taken from each jeweller’s own published opening hours.
35 of the 91 jewellers whose opening hours we hold are open on a Sunday. Hours change, particularly around bank holidays, so ring ahead before travelling. 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.
