About

The Name Is the Pitch

Buy Fine Diamonds is a plainly named, value-led diamond shop at 34 Greville Street. The catalogue runs from classic solitaires through halo, trilogy and vintage settings, with a design-your-own path built around GIA-graded stones and a ready-to-ship range for buyers on a clock.

Google shows 655 reviews. We analysed 610: 603 are five star, four are four star and three sit at one star, in a record of seven years. The pace is the headline: 326 of the 610 arrived in the past twelve months, which puts them on our Fastest Growing and Most Reviewed lists.

One detail worth noting for budget-conscious buyers: metals run from 9ct gold up to platinum. Most of the quarter starts at 18ct, so a 9ct option moves the same stone budget further into the diamond.

Three hundred and twenty-six reviews in the past year, 603 of 610 analysed at five star, and settings from 9ct gold up.

What reviewers say

610Reviews analysed

603Five star

7Years of reviews

The themes spread evenly across what matters: 27 reviewers describe the bespoke and design process, 26 depth of knowledge, 25 good value for the money and 24 patience with questions. Ten say there was no pressure to buy, earning a place on our No-Pressure Jewellers list, and seven mention a quick turnaround.

Three reviews sit at one star against 603 at five, and they reply to 39 per cent of reviews, so there is a public record of how issues get handled.

For scale: that record sits in the top 5 per cent of the 311 for review volume. In plain terms, you should be in safe hands here.

You can really trust these guys. If you are looking for diamond jewellery you really do not need to go anywhere else. I have used this company a few times now over the course if 10 years. I admit I am not in the market for anything really expensive or bespoke.”

BuyFineDiamonds was a blessing in disguise for myself. I was looking for a bespoke engagement ring and was struggling to find a vendor who could do it fast and to the highest of standards whilst maintaining a competitive price. I met Ravi and he was extremely helpful.”

Who this suits

The Right Buyer for Buy Fine Diamonds

This suits a buyer working to a defined budget who wants it spent on the stone. The 9ct-to-platinum metal range, the value theme in the reviews and the open catalogue all point the same way, and the GIA grading keeps the stone side honest.

It also suits a buyer who wants recent evidence: over half the analysed record arrived in the past year. Appointments are advised; the shop sits on Greville Street a minute from the main Hatton Garden run.
