Our verdict

Ranked #29 of 311 on 335 analysed reviews, 333 of them five star, across one of the longest records in the quarter. Breadth is the draw: new, vintage, pre-owned and loose stones, priced to the office format rather than a shop front.

About

Private Offices Rather Than a Shop Window

Diamond Rocks run one of the larger catalogues in the quarter, over 5,000 pieces spanning new, vintage-inspired, antique and pre-owned jewellery plus loose diamonds, from private offices at Suite 109, 100 Hatton Garden. Their stated reason for the office format is lower costs passed on to the customer, and the business is a member of the National Association of Jewellers.

Google shows 338 reviews. We analysed 335: 333 are five star and two sit at one star, across more than seventeen years, which is one of the longest review records of any jeweller we rank. Forty-four arrived in the past twelve months.

The range runs wider than most: design-your-own rings in natural or lab-grown diamonds, gemstone rings from sapphire to tanzanite, vintage and pre-owned pieces, and interest-free Klarna finance on the catalogue.

More than seventeen years of reviews, 333 of 335 analysed at five star, from private offices above the street.

What reviewers say

18Years of reviews

Depth of knowledge leads the themes with 22 mentions, with 21 citing good value for the money and 19 the bespoke and design process. Eighteen reviewers say their partner loves the ring, and thirteen mention aftercare and resizing.

Two reviews sit at one star in more than seventeen years. They reply to few reviews, so the record is customers describing the work rather than a running conversation.

For scale: that record sits in the top 13 per cent of the 311 for review volume. In plain terms, you should be in safe hands here.

My husband and I cannot recommend Diamond Rocks highly enough. From start to finish, the service we have received has always been impeccable. Vineet, has been our trusted jeweller for the past six years. Every single time, he goes above and beyond to make the entire experience seamless and enjoyable.”

I cannot recommend Diamond Rocks highly enough. I have been purchasing diamond jewellery from Vineet for the past 11 years and have now bought six pieces in total , every single one has been exceptional. Vineet is incredibly knowledgeable, patient, and trustworthy.”

Who this suits

The Right Buyer for Diamond Rocks

This suits a buyer who wants breadth: new, vintage, antique, pre-owned and loose stones under one roof, with the whole catalogue browsable online before an appointment. The value case is explicit, offices rather than a showroom, and the review themes back it up.

It also suits anyone drawn to a vintage or pre-owned ring, which most of the quarter does not carry in this depth. Appointments are advised; the suite is inside 100 Hatton Garden rather than behind a window.
