About Sunshine Diamonds
Sunshine Diamonds is a London jeweller with a showroom in Hatton Garden, the city's traditional jewellery quarter. It sells engagement rings, wedding bands, diamond earrings, tennis bracelets, pendants and gemstone pieces online, with prices in pounds, and describes itself as a manufacturer selling direct to customers rather than through a high street middleman.
Most designs can be configured before you buy. You choose between natural and lab-grown diamonds, pick the carat weight, and select the metal, from 925 silver and 9K gold up to 18K gold and platinum, so the same ring or bracelet can sit at very different price points. There is also a Ready to Ship range of in-stock pieces for anyone short on time, and the team takes on bespoke commissions. Pieces are UK hallmarked, and the site lists a five-year guarantee and a diamond and valuation certificate.
Delivery is free and insured, including international orders, and the returns page offers a 30-day money-back policy with free return shipping plus one complimentary resize. The Hatton Garden showroom opens Monday to Saturday by appointment, and virtual consultations are available too. Finance is offered through PayPal Credit, including 0% for four months on spends of £99 or more.

Ways to save at Sunshine Diamonds
Compare natural and lab-grown versions of the same design: the stone type is a setting on most product pages and changes the price a lot.
Try the metal options too; 925 silver and 9K gold versions are usually far cheaper than 18K gold or platinum.
If you need a piece quickly, shop the Ready to Ship range: in-stock orders cleared before 3pm are dispatched the same day.
Spending £99 or more? PayPal Credit offers 0% interest for four months at checkout.
