About

Always Bespoke, Forever Unique

Kensington Parker’s own line is the whole pitch: always bespoke, forever unique. There is no ready-made collection; every piece is commissioned, designed and made to the client, from a base at 53 Duke Street on the Mayfair side of Oxford Street.

Google shows 116 reviews, and every one of them is five star, across more than eight years. Fourteen arrived in the past twelve months, and just over a quarter of reviews carry a reply. Andrea is the name reviewers mention.

The site is a lookbook rather than a shop, with an education section for first-time commissioners, and the working hours run long: into the evening on weekdays, with weekend appointments too.

No ready-made case to choose from: everything commissioned, and 115 of 115 analysed reviews at five star.

What reviewers say
115Reviews analysed
115Five star
8Years of reviews

The bespoke and design process dominates with 19 mentions, depth of knowledge follows on 13, and eight reviewers describe patience with questions. Seven say the partner loves the ring.

There is nothing below five stars across eight years, in a commission-paced record.

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.

Kensington Parker - Quality Jewellrey and outstanding service. When we first approached Kensington Parker, we had a vision but very unsure we would be able to get what we wanted, within the budget we had.”

I had the absolute pleasure of working with Andreas to design a beautiful bespoke engagement ring for my fiancée, and I couldn’t recommend him highly enough. From the moment I visited his beautiful office in Bond Street, I felt completely at ease.”

Who this suits

The Right Buyer for Kensington Parker

This suits a buyer who has already decided on bespoke and wants the whole conversation built around their commission rather than steering off a display case. The education pages are a good pre-appointment read for a first-timer.

The evening and weekend hours suit working buyers. Less suited to anyone who wants to try on a wall of ready-made rings; there is none here, by design.

The evidence behind this guide

This is the only place online that ranks London's engagement ring jewellers on review evidence. I screened 1,120 London businesses, verified 305 as genuine engagement ring jewellers, and re-crawl their Google reviews every month, 57,304 reviews at the last count. Every listing is checked for district, walk-in access, natural or lab-grown stones and opening hours before it appears. The method is published in full on the Top 100, and rankings cannot be bought: editorial policy.
