Sunshine Diamonds discount code 2026 — international shipping, payment & best offers

Sunshine Diamonds discount codes on Koubonat

Sunshine Diamonds is a jeweller and jewellery manufacturer based in Hatton Garden, London's historic diamond quarter. It sells direct to customers through its website rather than through high-street chains, and says this cuts out middleman costs and keeps diamond prices closer to the workshop. The team cites more than 50 years of experience in the diamond and gemstone trade and describes itself as one of the early UK jewellers to let shoppers customise jewellery online.

AUTUMN18 takes 18% off sitewide, and DECADE65 brings the 1 carat lab-grown diamond studs down from £699 to £249. Both codes are open to all regions according to the advertiser, and UK delivery is insured and free. This guide collects the live Sunshine Diamonds codes on Koubonat (AUTUMN18 and DECADE65) plus what to know about international shipping, payment, and returns before ordering.

What to buy at Sunshine Diamonds

• Engagement rings: Solitaire, halo and three-stone settings in natural or lab-grown diamonds; the 18% from AUTUMN18 matters more as carat weight rises.
• Diamond earrings: 1 carat lab-grown studs for £249 with DECADE65, or drops and small hoops if you want a different look.
• Tennis bracelets: A 5 carat lab-grown tennis bracelet in 9K white gold is the Deal of the Week; measure your wrist first since length changes the stone count.
• Wedding bands: Men's and women's bands, plus bands shaped to sit flush with an engagement ring; order them in the same basket so the code covers both.
• Necklaces and pendants: Solitaire pendants and coloured-stone necklaces in sapphire or emerald; good gifts for engagements and family occasions.
• Bespoke and custom jewellery: Change the metal, carat, colour and clarity or commission a new design; custom pieces take around 15 working days and may sit outside the normal return rights.

Buying from Sunshine Diamonds by country

• The United Kingdom: The UK is the home market: free insured Royal Mail delivery, same-day dispatch for ready pieces paid before 3pm, and the option to visit the Hatton Garden showroom by appointment.
• Europe: Orders to Europe go by FedEx, but since Brexit local VAT and customs charges may apply on arrival, so add them before comparing prices.
• The United States: Shipping to the US goes by FedEx with prices in GBP, and both codes are open to all regions; check US import charges on jewellery before you order.
• The Gulf & Middle East: The store ships internationally by FedEx, insured to the door, so you can order to Saudi Arabia, the UAE, Kuwait, Qatar, Bahrain, Oman and Egypt, but customs duty and VAT in your country are paid by you on delivery. AUTUMN18 and DECADE65 are listed for all regions, and the saving can still be real after charges, especially on lab-grown diamonds. Confirm your ring size before ordering because international returns take time.
• The rest of the world: Elsewhere: international delivery is available by FedEx, prices are in GBP, and local charges are on the buyer; your bank may add a small currency conversion fee.

Smart saving tips

High-street jewellers carry shop and middleman costs, while Sunshine Diamonds sells straight from the workshop, and a code adds a further saving on top. On a £1,500 engagement ring, for example, AUTUMN18 saves about £270, and DECADE65 makes the 1 carat studs £249 instead of £699. Always compare diamond type (natural or lab-grown), colour, clarity and metal between stores, because the price gap between natural and lab-grown is large. Sunshine Diamonds runs a 30-day money-back policy: you can return, exchange or resize a piece within 30 days of purchase, the store pays return shipping, and you choose store credit or a refund to your bank account. Collection and drop-off can be arranged by phone, or you can hand the piece in at the London showroom. Items made to your special requirements are excluded from the standard 14-day cancellation right in the terms, so ask about your piece before ordering. The 5-year manufacturing guarantee covers workmanship faults after inspection.

Best seasons to buy: The Autumn Diamond Event in October — 18% off sitewide with AUTUMN18, Black Friday and Cyber Monday in November — usually the strongest diamond sales in the UK, Before Valentine's Day in February — heavy demand for pendants and studs, so order early for custom pieces, Spring and summer engagement and wedding season — a good time to buy the ring and bands together.
