FineDiam voucher codes apply to diamond jewellery made in Hatton Garden, London: engagement rings, wedding bands, earrings, bracelets and necklaces. UK shipping is free, Ready to Ship pieces leave the same or next working day, eligible items can be returned within 30 days of delivery and financing is advertised. The Terms of Service of FineDiam Ltd are binding.

“If you want to keep the option of a return, choose a Ready to Ship piece rather than a ring made to your size: eligible items can go back within 30 days of delivery, whereas rings made to a requested size, engraved and bespoke pieces usually cannot be returned unless faulty.”

It depends on how far production has gone. FineDiam asks you to cancel within 24 hours where possible.

How do I start a return with FineDiam?

Contact FineDiam before sending anything back, by email to sales@finediam.com, giving your order number, full name, contact details, the reason for the return and photographs where relevant.

FineDiam: diamond jewellery from Hatton Garden, ready to ship or made to your design

FineDiam is a London jeweller with its studio in Hatton Garden. FineDiam Ltd makes engagement rings, wedding bands, earrings, bracelets, necklaces and bespoke pieces, working directly with its master craftsmen and offering both natural and lab-grown diamonds. The shop suits you if you are planning a proposal, a wedding or an anniversary and want certified stones and UK hallmarked metal.

You can buy a finished piece for next day UK delivery or have a ring made to your own specification, and a voucher code from save-up.co.uk makes the order cheaper.

The FineDiam range from solitaires to tennis bracelets

The menu of FineDiam is built around rings, but tennis bracelets, pendant necklaces and earrings take up a large part of the shop. Diamonds can be chosen in eight shapes, from Round and Oval to Pear, Marquise and Radiant, and the metals range from 9k and 18k gold in yellow, white and rose to 950 platinum. Styles include Pave, Solitaire, Three Stone, Hidden Halo, Vintage and Halo.

  • Engagement rings: solitaire, side stone, halo, hidden halo, cluster and bridal set rings
  • Wedding rings: full and half eternity, pave set, wishbone, bubble and fancy rings
  • Gemstone rings: sapphire, emerald and ruby
  • Earrings: stud, drop, hoop, halo and gemstone earrings
  • Bracelets and necklaces: diamond tennis bracelets, tennis necklaces, pendants and chains

Ready to Ship pieces leave Hatton Garden the next working day

The Ready to Ship collection is what sets FineDiam apart for a last-minute gift. It listed 3706 results, and every piece in it is finished, hallmarked and sent from the Hatton Garden studio the same day or the next working day; the homepage sums it up as «Find it today. Wear it tomorrow.» UK shipping is advertised as free and insured. Stock is limited, so a piece shown today may be gone tomorrow. Because these items are standard stock, they also keep the 30-day return window for eligible items, unlike pieces made to your specification.

Bespoke rings, appointments and aftercare

If nothing in the range fits, the «Build Your Own» service lets you start from an existing design or from scratch: change the metal, pick a diamond, adjust the setting or add an engraving. A virtual appointment can be booked from the menu, and the team can be reached by phone, WhatsApp or email at sales@finediam.com. The homepage advertises free ring resizing, a lifetime warranty and easy financing. Keep in mind that made-to-order pieces need extra production time and usually cannot be returned, and that cancelling after 24 hours can cost up to 30% for lab-grown diamond jewellery once work has started.

How to save at FineDiam

Many FineDiam pieces already show a reduced price beside a higher original price, and the four price bands from Under £500 to Above £2000 help you stay within budget. A voucher code is entered at checkout; check the deduction before paying, as FineDiam may change prices without notice and only confirms an order after reviewing it. A code pays off most on a returnable Ready to Ship piece, since bespoke work carries cancellation charges.

If you are comparing jewellers, save-up.co.uk also lists further Jewellery & Watches shops with voucher codes, such as Molly Brown London Voucher Codes, Jewel First Discount Codes, Philip Jones Jewellery Promo Code and Argento Voucher Code.
