The moment you start shopping for an engagement ring, Google greets you with thousands of jewellers, discount codes and diamond jargon. But a proposal deadline doesn’t leave room for trial-and-error. You need a shortlist you can actually trust—places that combine sparkle with solid guarantees—so you can get back to planning the perfect yes.

This guide hands you 15 reputable options across the UK, from boutique workshops in Hatton Garden to online giants with next-day delivery. Each jeweller earned its spot through independent diamond certification (GIA or IGI), transparent pricing, strong customer reviews, ethical sourcing and warranties that last beyond the wedding day. A few quick facts before we start: couples typically spend £1,800–£5,000, the ‘three-months’ salary’ rule is marketing fluff, and Hatton Garden can be up to 50 % cheaper than the high street. We’ll begin with family-run A Star Diamonds, then work through fourteen equally reliable alternatives.

1. A Star Diamonds (Hatton Garden, London)

If you’re wondering where to buy engagement rings UK couples rave about, start on the cobbled streets of Hatton Garden. A Star Diamonds is a family-run studio where the people who design your ring are the same craftsmen who set the stones a few metres away in their basement workshop. No middlemen, no stockroom guesswork—just sketches, CAD renders and wax models until you’re happy.

What makes them stand out

• Bespoke only: every ring begins with a one-to-one consultation with a GIA-trained gemologist.
• Ethical first: choose between responsibly mined natural diamonds or 100 % conflict-free lab-grown stones.
• Total transparency: you see the loose stones, compare GIA/IGI certificates and approve each stage before the ring goes into production.
• UK-made craftsmanship backed by lifetime aftercare (polish, clean, health check).

Price range & buyer policies

Typical bespoke quotes start around £1,200 for a lab-grown solitaire and £1,800 for a comparable natural diamond; final cost scales with the 4Cs and metal (platinum, 18 ct yellow, white or rose gold).

• Complimentary engraving, discreet insured shipping and a 30-day return window on non-custom items.
• Free resizing for life and an annual spa-day polish—handy if the ring collects London grime.

Ideal for & any drawbacks

Perfect for couples who want their love story translated into metal and sparkle, and who value meeting the maker. Do book early: the design-to-proposal timeline runs three to six weeks, and walk-ins aren’t a thing—those personal appointments keep the diary tight.

2. Taylor & Hart (London & Online)

Taylor & Hart sits comfortably between boutique atelier and slick e-commerce. From its showroom near London Bridge—or your sofa via Zoom—the brand walks you through every decision, down to the tiny ruby discreetly set inside each ring as its maker’s mark. If you like the idea of almost-limitless custom options but still want someone to hold your hand, this is a compelling pit-stop on your “where to buy engagement rings UK” checklist.

Signature approach

• Bespoke by default: you pick the setting, metal and diamond, then receive free 3D renders and one round of design tweaks.
• Choice of GIA-certified natural diamonds or IGI-certified lab stones, many with blockchain provenance reports for extra peace of mind.
• The hallmark “Signature Ruby” hidden in the shank adds a romantic Easter egg, symbolising passion and good fortune.
• Dedicated design consultant from first sketch to final polish, whether you visit in person or order online.

Buying experience

Average spend ranges £1,500–£6,000, but you can go lower with smaller lab diamonds or higher if you fancy a two-carat stunner.

• Finance plans up to 60 months (0 % for the first 12 on selected rings).
• Lifetime manufacturing warranty, free resizing within 90 days and complimentary annual check-ups in their London or New York studios.
• Insured global shipping; UK delivery is next-day once the ring is finished.

Who will love it

Couples craving full creative control yet unwilling to sacrifice expert guidance; tech-savvy buyers happy to approve CAD renders from home; romantics smitten with the hidden-ruby signature touch.
