Absolutely lovely!

I ordered the one carat diamond eternity band as a gift for myself - the ordering process was a breeze! I also opted to finance the purchase, it was easy...quick approval, affordable payment options and made buying the ring a reality today not in a few months! I also ordered the wrong size ring and I had a replacement shipped to me the next day! Amazing!!!

I will be back to add more beautiful pieces in the (near) future! I have also referred a number of my friends and family to the website and shared my great buying experience with them!

Wedding band super quick delivery

Band is gorgeous. Delivery was quick and simple. Delivery was within a few days of ordering. Thank you


Their customer service team was so responsive and helpful. I had to make an exchange for a different size and they made it so easy for me! Love my jewelry so much! Wonderful company.

1 Carat Diamond Eternity Band

The ring is gorgeous and the shipping was incredibly fast. Company is very responsive via email. The only issue I had was I ordered my usual ring size and it is too small. Noemie is sending a ring sizer to find out my correct size with them. Shipping is so fast I’d recommend verifying your size first. I was also first planning to purchase the ring in platinum which is a custom order and they graciously offered to send me a ring in stock for my wedding fill in until the custom order was completed. My fiancé ordered from Brilliant Earth and had many issues. Hopefully they start selling men’s bands in the future! I will definitely order again!

Most sparkly ever!

I ordered 2 eternity bands- the 1CT and the 1/3 CT and both exceeded expectations. I’ve been an exclusive Blue Nile shopper until now - and I’m so glad I found Noémie!!
