She loves the ring.
Cut is the absolute most important of the 4C's and the Signature Round Diamond's are comparable to the very best cut diamonds from any other retailer. This diamond sparkles brilliantly in any light and appears much larger than it really is due to the cut.

It's so sparkly!
The diamond was beautiful. For something of similar size and quality from a local jeweler I would have had to pay more than twice as much. I was extremely happy with this diamond and so is she! The assistance over the phone is second to none. It takes moments to talk to a real person and the directories are kept to an absolute minimum on the phone. They are great people.

Destined to be a family heirloom.
I was told buying a diamond on-line was like buying a house without a realtor -- so wrong! The selection is without comparison and the final choice stunning!!!

Absolutely Perfect, it sparkles from quite a distance.
I researched and shopped online and at several local stores and Blue Nile by far has them all beat in quality, customer service and pricing. You get what you pay for.

Wonderful Engagement Ring
My friends had told me very good things about Blue Nile and they were right! My fiancee loves the ring I bought for her and often tells me how "sparkly" it is. Not only is the quality of the diamond exceptional, but they ship it fast and safe. I would highly recommend Blue Nile!

Both of us loved the RING
I must say I did a lot of research on Diamonds. The 4 C's And I looked on all kinds of websites. And for a great cut and color and size a Blue Nile Diamond is such a great deal. When I opened the box it took my breath away. It was so beautiful.

Stunning Diamond
This is his fiance here. We love the diamond. It is exceptionally clear and has that "fire" everyone speaks of. It is just stunning. I may even venture to say he loves it more than I do, if that is possible. I often find him staring at the ring lovingly and am tempted to say "Hey! up here!" Thanks Blue Nile!

She can't stop looking at the fire and sparkle!
I was really pleased with the ring when it arrived, it exceeded my expectations and she absolutely loved it when I proposed. She can't stop looking at it to check the fire and sparkle of the diamond under different lights. Simply stunning! Glad I went for the ideal Signature Cut and appreciated the advice on the size, it fits perfectly! Thank you!

Amazing value and customer service.
I will highly recommend Blue Nile to family and friends. The diamond I purchased was significantly better quality than I would have gotten for the same price in most stores. The customer service and next day delivery was amazing. Also, the 30 day return policy was necessary for my piece of mind, however there is no doubt that we're keeping the diamond after getting it appraised.

The signature round diamond is the brightest most beatiful diamond I have ever seen. Set in the ring it just makes the whole ring eye catching. This diamond ring is a surprise for my wifes 40th wedding anniversary, and I am sure she will love it! Thank you so much Blue Nile.

The quality of the ring is beyond what I expected. There are cheaper diamonds that might have been as good, but I liked the option to upgrade and the look is amazing!

This will become the best engagement ring ever!
The day that I got my diamond in the mail I took it for an independent assessment low and behold I got exactly what I wanted and payed for. I was very happy with the fast shipping, the ease of the website, and most importantly the overall quality and perfection of the diamond.

The ring was beautiful and she loved it. The quality seems to be better than shopping at a retail store with better overall value. The process of selecting is made very easy and there is plenty of information on the website to help with decision making.

She was moved!
I am not an expert on diamonds, but after getting accustommed to looking at a few jewelry stores and different specifications, I was truly impressed as soon as I opened the Blue NIle box and see the contrast to some of the one's I've seen at the store. It was a 'Wow' experience. Bottom line, my fiance was moved and truly loved it, and mission was accomplished, as her feelings was the ultimate measure.

She loves her engagement ring!
The Signature Round diamond shines brilliantly. Many have commented that the ring sparkles more than any other they have seen. I'm very happy with my decision to go with the Signature Round and my fiancee loves both the diamond and the Nouveau diamond setting.

Selection was awesome. The diamond is amazing. The ring is gorgeous. Even the box it came in was beautiful. This was my first time making a jewelery purchase on-line, and Blue Nile made it a great one. I will definitely be back.
