Perfect

Exactly what I wanted. Band is petit and elegant, and the diamond is beautiful and sparkly. I did the platinum band with a little over 1ctw round Astor Ideal cut.

Beautiful ring!!!

I bought this ring and paired it with a 1.8 CT round diamond. My (now) fiance loves it! She gets nothing but compliments on it, which makes me very happy. In terms of my overall experience with Blue Nile, it was fantastic. I really liked the customization and transparency in terms of being able to pick out which diamond I wanted.

Perfect Engagement Ring

"Yes!" was the answer. The ring is perfect and carries incredible sparkle. I paired it with a 1.2ct round center diamond. The diamonds in the setting provide beautiful accompaniment to the center piece.

She loved it!

Purchased a brilliant round 2.04 carat diamond with a petite four prong setting. Amazed at how quickly it was delivered and how readily available and nice the customer service personnel were. She absolutely loves the engagement ring and can't stop staring at it!
