Finediam is a fine jewellery business trading as FineDiam Ltd from Greville Street in London's Hatton Garden jewellery quarter. It sells engagement rings, wedding and eternity rings, earrings, bracelets, necklaces and pendants, with a strong focus on lab-grown diamonds alongside a smaller range of natural diamond and gemstone pieces.
Product names state clearly whether a stone is lab grown or natural, and many listings mention IGI certification and UK Assay Office hallmarking. Most pieces are made to order in a choice of 9k or 18k gold or platinum, which the shop says takes around two to three working weeks, while a ready-to-ship range is sent out for next-day UK delivery. A bespoke design service and showroom visits by appointment are also offered.
UK delivery is free and insured. Eligible standard items can be returned within 30 days if unworn, though made-to-order, resized or engraved pieces usually cannot be returned for a change of mind. One free resize is included within 30 days of purchase, and the warranty covers manufacturing faults for the first year.
