She said 'YES!!'
Very very beautiful Diamond and Ring with amazing quality and detail. Worth every penny!





Amazing quality, amazing price.
Took my breath away when I opened the box. The diamond was set in a tension clasp allowing me to get a perfect view of it without worrying about dropping it and whatnot. The quality is amazing and the price was one step beyond that! I can't say that I've ever been more satisfied with an online purchase.





Diamond has a great sparkle to it and the additional certificate was nice to get.





Beautiful diamond
The princess cut signature diamonds are exceptional,very bright and full of sparkle,my jeweler was amazed at the quality. I will definitly be shopping with blue nile again!





Exceptional value, she loves the sparkles!
After extensive shopping and comparisons between jewelers, Bluenile has the best pricing of all. The Princess cut that I purchased sparkles brilliantly and she just loves it!





Engagement Ring
For princess diamonds, you have to get the highest quality cut. Even though there is no GIA cert for Ideal cuts for Princess diamonds Blue Nile still manages to find the best cuts that exceed the "excellent" GIA cert.





She loved the diamond.
I was very impressed at how quickly the ring arrived. I ordered my signature cut diamond on a Friday morning and received it at work before lunch on Monday.
The diamond lived up to all my expectations.





More beautiful than I imagined.
We discussed getting a 25th Anniversary Ring for my bride. I gave it to her last night. Her quote "It is so brilliant - more beautiful than I ever imagined". I agree.





WOW so glad I went with Blue Nile the signature cut was worth every penny we always catch people just staring at the ring everywhere we go makes me smile knowing my girl has the best thanks for helping me make her dreams come tru





Her Fairy Tale came true!
I took the suggestion from friends who have shopped at Blue Nile in the past and bought an engagement ring for my girlfriend. Needless to say it was an exceptional ring and I was really impressed with the service I received. As for my girlfriend, she loved the ring and shows it off every where we go, and you wouldn't beleive the compiments she receives on the ring on a dailly basis.





The quality and craftsmanship are extreme. I am surprised at how clear the diamond is and the detail of the setting. Highly recommend.





"Perfection"
It sparkles in the dark. I can find nothing wrong with it, and as a self- proclaimed perfectionist, that's huge for me. I am in love with my ring and more in love with my fiance for giving it to me.





She adores her wedding ring
I was very impressed with the Signature Cut Princess Daimond. The cut clearly makes a difference in the "sparkle" of the daimond. I was equally impressed with the delivery to Hawaii; order by 4 pm and get next day delivery. Everything went as planned and my wife just adores the ring; both with the center daimond and the setting. It was well worth the purchase price. I'm glad I took the time to visit your website. I am a very satisfied customer.





Fantastic
The diamond sparkles in even the dullest of light and shines with rainbows in pure daylight. She loves it more than me, I'm afraid.





Gorgeous cut, signature cut is the way to go. Setting is fantastic. It's "sparkling presence" is undeniable.





Amazing ring, amazing price.
"Signature cut" exactly what the title says, this diamond was the most beautful I have seen and I can
Not wait till I can give it to the love of my life.





Couldn't have been better!
This diamond was brilliant. Signature Ideal Cut is the way to go. This diamond light hits the diamond at every angle. Platinum four prong setting is simple, but dfinitely makes the stone look even larger.





she loved the ring!!
This was an excellent choice. Really dances in the light. If you have the budget go with the signature ideal you won't regret it.





The Blue Nile Signature Cut is the only way to go. Her eyes sparkle just as much as the diamond when she sees it!





Blue Nile was highly recommended by my peers who have more knowledge in jewelry purchase. I found the LIVE CHAT customer service to be extremely helpful and allowed me to narrow down my choices more easily. Customer service did not try to up-sell and provided great recommendations that met my budget.





Beautiful and great price! Service was superb!
Beautiful! She loved and I'm happy I got a great deal on it after having checked the competition! Great and fast service/delivery!





Surpassed my expectations and hers.
I could not believe the stone when i first saw it. It was clearer and sparkled more than any stone i had looked at in a jewellery store. Service was great and can't beat the price..





I told her we had 30 days to return it and get something else, she is the one wearing it - she said no chance, it was beautiful





A ring to behold.
My diamond decision came after much research and "shopping around." In the end, I wanted to be sure that the ring I received was of the value I was paying for. I went with Blue Nile and was not let down. This ring shines and the value and service were unbeatable. A++





It was her dream diamond realized.
It was an incredibly beautiful diamond and sparkled more than I could have imagined. It was worth the price and i received excellent customer service. I highly recommend princess cut diamonds since they are very beautiful.





She loves the ring!
Looks amazing. It sparkles! She loves it. Customer helpline was very helpful in making decision. Blue Nile's diamond education proved true- I followed its guidelines and am very happy!





Excellent. My search ended here.
Can't wait to give this to my fiancee-to-be. 'Vintage' is just her thing, and this ring is everything vintage, timeless, classic, effeminate, delicate, and beautiful. Just like her.





very happy with purchase
I loved the Diamond when it arrived. I matched the ring to the ladies rings at our work and they all loved how it sparkled with fire outshining their bigger more expensive rings. I didn't have a lot of money so I went with a smaller diamond that was of better quality. My girl loved the ring and that is all that mattered to me.





The Sparkle is amazing
The sparkle of the diamond is by far the best I have seen in my search for the perfect ring.
