Best credit card to use at Blue Nile.

Online Shopping

Blue Nile pioneered buying engagement rings online, letting shoppers customize diamonds at bluenile.com, where checkout codes as online shopping or general retail. Ring purchases run large, so even a modest flat or online multiplier returns real value on a single order. Jewelry carries no dedicated bonus tier, making a high everyday-earning card the sensible choice here.

Picks without a tag earn at Blue Nile both in-store and online. Watch for theOnline onlytag — those bonuses only apply on bluenile.com.
