Hatton Garden is brilliant for choice, but that’s exactly what makes it tricky. With dozens of jewellers clustered together, it’s hard to know who’s reputable, what a fair price looks like for a 1ct diamond ring (natural or lab grown), and whether you need an appointment or can simply walk in. If you’re planning a proposal or shopping for wedding bands, you don’t want your weekend to disappear to showroom hopping—or to pay over the odds because you couldn’t compare like‑for‑like.

This guide trims the noise to five trusted Hatton Garden jewellers worth your time—A Star Diamonds, Queensmith, Holts Gems, Mouza Fine Jewellery and Daniel Christopher. For each, you’ll find what they’re known for, real-world reputation highlights, an honest price guide for popular settings and stones, opening times, and exactly how to book or visit. We’ll also share quick prep tips before you go—what to bring, what to ask, when to negotiate, and which certificates matter—so you can shop confidently and make a decision on the day. First up: A Star Diamonds.

1. A Star Diamonds

A Star Diamonds is a family-run Hatton Garden jeweller focused on bespoke engagement rings and wedding bands. You’ll work directly with in-house designers, goldsmiths and gemologists to shape a UK-made piece that reflects your story—whether you choose an ethically sourced natural diamond or a 100% conflict‑free lab-grown stone. Expect personal guidance, transparent education and meaningful lifetime aftercare.

What they’re known for

Reputation and reviews

As a boutique, people choose A Star Diamonds for attentive, one-to-one service and expert, plain-English guidance. The team’s mix of designers, gemologists and bench jewellers builds trust, while UK-made manufacture and lifetime aftercare reinforce quality and accountability many shoppers look for from Hatton Garden jewellers.

Price guide

Pricing depends on design complexity, metal, and the diamond’s cut, colour, clarity and carat. Lab-grown diamonds typically offer larger sizes for the same budget versus natural. For a fair comparison, ask for like‑for‑like quotes:

• Match specs: Same shape, carat, cut grade, colour, clarity, fluorescence and certification.
• Separate costs: See diamond and setting priced individually.
• Certificates: Request GIA/IGI report numbers for verification.
• Aftercare value: Factor in free resizing/polishing and engraving.

Opening times

Consultation availability is best confirmed via their booking page or by contacting the studio directly. Hatton Garden includes both appointment-led and walk‑in experiences, but for bespoke design it’s wise to secure a slot—especially for Saturdays and peak seasons.

How to book and visit

Book an appointment online or reach out by phone/WhatsApp to share your ideas. Bring inspiration images, an outline budget, any deadlines, and preferred diamond type (natural or lab-grown).
