Lab-grown diamonds are now easy to find in the UK, from high street chains to independent jewellers in London's Hatton Garden and Birmingham's Jewellery Quarter. The question is no longer *whether* you can buy one, but *where* gives you the best combination of choice, quality and value.
1. High street jewellers
Pros: you can see and try pieces in person, easy returns, familiar brands. Major names such as Pandora now sell lab-grown diamond collections in the UK.
Cons: ranges focus on ready-made designs and smaller stones; less room for customisation.
2. Independent jewellers (Hatton Garden, Jewellery Quarter)
Pros: expert advice, bespoke design and the chance to choose a specific loose diamond.
Cons: quality and pricing vary between shops, so compare several.
3. Online retailers
Pros: huge choice of certified loose stones with photos, videos and reports.
Cons: you can't see the stone in person, so the return policy and certificate matter even more.
4. Direct from a manufacturer
Pros: closest to the source, with the ability to choose exact specifications. Ideal for jewellers, designers and buyers who want something bespoke.
Cons: you handle more of the process yourself, including shipping and import paperwork.
What to check wherever you buy
- The stone is described as laboratory-grown (or lab-grown), never simply "diamond".
- There is an IGI or GIA report for centre stones, with the report number laser-inscribed.
- Gold and platinum items sold in the UK above the legal weight thresholds carry a UK hallmark from an Assay Office.
- Clear return and resizing policies.
Importing from abroad
If you buy directly from overseas, import VAT (currently 20%) and any applicable duty are normally due when the parcel enters the UK, and couriers may charge a handling fee. Factor this into your comparison.
For UK jewellers
If you are a UK retailer or designer, working directly with a manufacturer gives you consistent stones and your own designs. See our price list or contact us.
