About Blue Nile
What you can buy
Engagement rings and loose diamonds are the core. Buyers can choose a stone to suit their budget, with help from diamond consultants if they want it. Wedding bands come next, followed by necklaces, earrings, bracelets and pendants. Independent certification arrives with every diamond, which makes comparing stones far easier for a first-time buyer.
Delivery to the UK
Parcels ship from the European distribution centre in Ireland and usually arrive within a few business days. Blue Nile acts as importer of record, so customs paperwork is handled for the buyer. Free shipping is available on selected items.
Returns and aftercare
A 30-day money-back policy covers purchases. Anything sent back has to be unworn and in its original state, and returns travel with a fully insured prepaid label. Craftsmanship carries a lifetime guarantee, and a price-match guarantee applies to diamonds. Gift cards are sold, and payment can be made by Visa, Mastercard, American Express or PayPal. Blue Nile also has a small number of showrooms alongside the website.
Sustainability at Blue Nile
Blue Nile is committed to ethical sourcing, offering only conflict-free diamonds that comply with the Kimberley Process. All diamonds are GIA-graded for quality assurance and transparency.
