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.

FAQs About Round Cut Diamonds
Round cut diamonds take the most raw material to create when they are cut from a rough diamond. While carat weights under .75 are only slightly more expensive than similar fancy cut diamonds, as carat weight increases (especially at the 1 ct. mark), the cost increases more significantly. Learn more in our guide to how diamond shape affects price.
Round cut diamonds are the only shape with cut standards established by the Gemmological Institute of America (GIA). All Blue Nile diamonds are GIA certified. Learn more about GIA diamond grading reports.
Round Cut is by far the most popular diamond shape on Blue Nile. Over 70% of our customers choose a round cut diamond.
Round cut hides inclusions well, so you may be able to save with a lower clarity grade.

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 customisation 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 centre diamond. The diamonds in the setting provide beautiful accompaniment to the centre piece.

She loved it!
Purchased a brilliant round 2.04 carat diamond with a petite four claw 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!
