FAQ
Where is Sunshine Diamonds based?
The jeweller works out of Hatton Garden in London, the UK's traditional diamond district, and has more than 50 years of experience trading diamonds.
Does Sunshine Diamonds sell lab grown as well as natural diamonds?
Both are stocked. Lab grown pieces come with IGI certification and natural stones can be supplied GIA certified, so you can compare the paperwork before you decide.
How much is delivery?
Delivery is free worldwide, so the figure you see at checkout is the figure you pay.
Which metals can I choose from?
Rings, bracelets, earrings and pendants are made in 9K gold, 18K gold and platinum, and each one carries a UK hallmark.
How do I know the diamond is genuine?
Every piece ships with a guarantee certificate, and the certificate number on a lab grown stone can be looked up directly on the IGI database.
What if my Sunshine Diamonds discount code will not apply?
Check the expiry date first, then check whether the item is already part of a separate deal, because a sitewide voucher code and a single item offer normally cannot be combined.
