Diamond Palace began in 1994 as a small family business in Hatton Garden, and Peter and Sheila have guided couples through the purchase for more than twenty years. The showroom is at 36 Greville Street, and by their own count they have made more than 10,000 rings.

Google shows 871 reviews. We analysed 850: 835 are five star, six are four star, and nine sit below that. The record runs back 13 years and is still growing, with 187 reviews in the past twelve months.

Natural and lab-grown diamonds are both on offer, and bespoke work starts from a published £2,500, with a CAD design to approve before anything is made.

Our Top 100 ranks every London business we could verify as a genuine engagement ring jeweller, 305 of them from a pool of 1,120 candidates, on the strength of their Google review evidence. Diamond Palace Jewellers ranks #22 of 305.

They also appear on four of our ranked lists: No. 10 on our First-Time Buyers list and No. 10 on our Most Reviewed list, and they are on our No-Pressure Jewellers and Lab-Grown Specialists lists.

This suits a first-time buyer. Thirty-three reviewers describe arriving as nervous novices and being walked through it, 27 mention no pressure to buy, and they are No. 10 on our First-Time Buyers list.

It also suits a buyer who wants a bespoke ring with the terms set out in advance: from £2,500, roughly four to six weeks, a CAD design to approve before anything is made, and the making done in Hatton Garden.

Consultations are booked, in the showroom or virtually, so plan a visit rather than dropping in. Their rings come with a lifetime warranty and free resizing.
