Finediam is a Hatton Garden jeweller that sells mostly online, with showroom visits by appointment. Its range runs from engagement rings and wedding bands to stud earrings, tennis bracelets and pendants, and most of it uses lab-grown diamonds. Every product name says whether the stone is lab grown or natural, so you can see what you are buying. Many pieces are made to order in 9k or 18k gold or platinum, and a smaller ready-to-ship range is sent out next day. It suits couples ring shopping on a budget and anyone buying a jewellery gift who would rather have a bigger lab-grown stone than a small natural one.
What's worth a look
- IGI 0.53Ct D/VVS Lab Grown Oval Diamond Solitaire Ring 9k Gold Ready To Ship is currently £302 with the sale discount (£377 before it). It's a simple oval solitaire in 9k yellow gold with an IGI-certified lab-grown stone, and a sensible choice for a proposal on a tighter budget or at short notice.
- Ready To Ship D/VS 1.00Ct Lab Grown Round Diamond Stud Earrings in 9k White Gold are currently £215 (£269 before the sale). Plain round studs like these go with most outfits, so they make an easy birthday or anniversary present.
- 0.09ct Natural Diamond Lightning-Bolt Stud Earrings are currently £268 (£335 before the sale) in 9k white or yellow gold. They're one of the natural-diamond pieces, and a playful choice for someone who prefers small, quirky studs to classic solitaires.
- The Diamond Tennis Bracelets collection mixes lab-grown and natural designs in different carat weights and metals. Worth browsing if you want a statement bracelet for a milestone birthday. Prices vary a lot with stone size, so check the product page for each one.
Current offers
- A 20% Autumn Sale is running across the site, with the homepage countdown ending on 10 October 2026. The discount shows on product pages before checkout.
- UK delivery is free and insured, and ready-to-ship pieces can arrive next day. Made-to-order items take around two to three working weeks.
- One free ring resize is included within 30 days of purchase, where the design allows. Most rings can go up or down by about one size.
- Eligible standard items can be returned within 30 days if unworn and in their original packaging.
How to save more
- Look at the lab-grown version of a design before the natural one. The shop says lab-grown stones are typically 40 to 70% cheaper than mined diamonds of the same quality.
- Order within the sale window and choose a ready-to-ship piece if you can, as made-to-order, bespoke and resized items usually can't be returned if you change your mind.
- Get the ring size right before you order. Resizing is only free for the first 30 days, and full eternity rings usually can't be resized at all.
