About

Clarity, Spelled Their Way

Klarity London design diamond rings from a ground-floor studio at 36 Greville Street, with Peter the name that comes up in the reviews, appointments booked through an online calendar, and consumer terms stated plainly: free UK delivery and 30-day returns.

Google shows 90 reviews, every one of them five star, across more than seven years. The record has been quiet in the past twelve months, which reads as a studio working its order book rather than chasing the counter trade.

Depth of knowledge leads the themes, with aftercare and resizing behind it, in a record built steadily between 2018 and 2025.

Seven years, ninety analysed reviews, nothing below five stars.

What reviewers say

90Reviews analysed

90Five star

7Years of reviews

Depth of knowledge leads with twelve mentions and aftercare and resizing follows on six, in a record whose value is its consistency.

Nothing sits below five stars, and about a quarter of reviews carry a reply.

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.

Straight up, honest and genuine diamond dealers in Hatton gardens. Bought most of my wife's jewellery from Klarity and never had a problem. Everything is COA'd from GIA. Peter is a wonderful man, very knowledgeable and always accommodating to his clients. Any time my wife needs rings cleaning etc they always do without a fuss/problem.”

If there is a prize for the best jeweller in town, Klarity will definitely win the award - no competitions there! They may sell gems, but its the people in Klarity who are the true gems!”

Who this suits

The Right Buyer for Klarity London

This suits a buyer who wants a studio consultation on the quieter side of the street-level bustle, with the delivery and returns terms of an online retailer behind a face-to-face process.

The record is settled rather than fast-moving; judge it on the seven years of consistency and the conversation in the studio.
