Shopping for a lab-grown diamond can feel like navigating a minefield. You know you want the brilliance of a genuine diamond without the mined-stone price tag, but Google returns hundreds of retailers claiming to offer the best stones, the sharpest prices and the most transparent service. How do you separate the genuine craftsmen from the online middlemen? Which brands actually hold UK stock, and who simply dropships from overseas? When you’re about to spend thousands on an engagement ring, guesswork isn’t an option.

This guide cuts through the noise. We’ve vetted 15 trusted UK brands that specialise in lab-grown diamonds, from Hatton Garden ateliers and high-street chains to online-first jewellers with cutting-edge search tools. Each entry breaks down what the retailer does best, typical price ranges, who they suit and how the buying process actually works. Whether you’re hunting for a bespoke solitaire crafted in a London workshop or a quick-ship ready-made ring with next-day delivery, you’ll find clear recommendations to match your budget, style and timeline.

1. A Star Diamonds Hatton Garden

A Star Diamonds sits in the heart of Hatton Garden, London’s historic jewellery quarter, where a family-run team of goldsmiths and gemologists craft every ring on site. You won’t find mass-produced catalogue pieces here. Instead, you start with a blank slate and work directly with the designers to translate your vision into a one-of-a-kind engagement ring that captures your story. That level of personalisation, combined with London workshop credentials and lifetime aftercare, earns A Star Diamonds the top spot on this list.

Overview and why it leads this list

A Star Diamonds leads because it offers true bespoke service without the luxury-house price tag. You meet face to face (or via video call) with the craftsmen who will actually make your ring, and every design is drawn, rendered in CAD and cast in their own workshop. The business operates as an independent atelier rather than a high-street chain, so you receive expert guidance at every step rather than a sales pitch. Lifetime benefits include free resizing, polishing, cleaning and complimentary engraving, which means your ring stays in perfect condition for decades.

"We combine expert craftsmanship with ethical sourcing and offer significant lifetime benefits for our UK-made products."

Lab grown diamond range and bespoke services

A Star Diamonds stocks IGI and GIA-certified lab-grown diamonds in every popular shape, from classic round brilliants to modern cushion and oval cuts. Stone sizes start at 0.25 carats and scale beyond 5 carats, all guaranteed 100% conflict-free. The bespoke service covers solitaire, hidden halo, diamond band and trilogy settings in platinum, white gold, yellow gold or rose gold. Because everything is made to order, you can adjust prong styles, band widths and gallery details to suit your hand and lifestyle.

Price range and example budgets

Budget around £2,300 for a 1-carat lab-grown diamond ring set in 18ct gold, though final costs depend on your chosen clarity, colour and setting complexity. Smaller 0.5-carat designs begin closer to £1,400, while statement 2-carat rings stretch toward £4,500.
