About

Aftercare Promised for the Life of the Ring

Primo Diamonds work from The Record Hall on Baldwin’s Gardens, the trade building that houses several of the makers we rank, with GIA-graded stones, a create-your-own path from setting or diamond, quickship and lab-grown collections, and the standing term that leads their own pitch: a lifetime aftercare guarantee.

Google shows 75 reviews. We analysed 70, every one of them five star, across five years, with 22 from the past twelve months, and they reply to 99 per cent.

The first-timer threads run through the record, eleven reviewers saying the partner loves the ring and seven describing being guided through nervously, which earns a place on our First-Time Buyers list.

What reviewers say
70Reviews analysed
70Five star
5Years of reviews

Eleven reviewers say the partner loves the ring, ten describe the bespoke and design process, nine depth of knowledge and seven being guided through as a nervous first-timer.

Nothing sits below five stars, and 99 per cent 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.

I reached out to Primo Diamonds being a complete rookie and having left it fairly late to have an engagement ring made for my better half. From the first phone call, Francesco put my mind at ease; paying great attention to detail in my requirements and the fact that I knew nothing about diamonds whatsoever.”
Fabio Quadrozzi · July 2022 · On Google
I recently purchased an engagement ring from Primo Diamonds, and the experience was outstanding! I spoke with Francesco on the phone and then had a free consultation. During the consultation, I felt that he was incredibly knowledgeable, friendly, and helpful throughout the process.”

Who this suits

The Right Buyer for Primo Diamonds

This suits a first-time buyer who wants guidance now and cover later: the lifetime aftercare guarantee takes resizing and servicing off the worry list, and the guidance themes in the record are earned.

Appointments are advised; the business is inside The Record Hall rather than behind a window, so head for the Baldwin’s Gardens entrance.
