Beautiful Engagement ring
I was so pleased with the engagement ring I purchased in late June. My fiancé was thrilled with how beautiful the ring is and the diamonds are exquisite. I'm very pleased that I purchased Signature Ideal stones.

Simple and Elegant
I have been searching for a simple, everyday, elegant diamond necklace and finally took the plunge. This necklace is perfect. Diamond is of very good quality and it is exactly what I was hoping it would be. Building my own necklace allowed me to get exactly what I wanted without paying a fortune.

I've bought an engagement ring.
I've bought a signature cut diamond ring. When I tried place an order, I wasn't sure if I liked it because it was difficut to tell its quality and authenticity from the picture. However, the skepticism was vanished immediately after I received the ring via Overnight Priority mail. It was a pure beauty. I am a man and a soldier. I don't really get sentimental over a little piece of jewelry, but it was differernt. It was a breath-taking. When I proposed to my girl with this diamond ring, she absolutely loved it and couldn't take her eyes off from it for a while.
I did not regret single penny I have spent on this ring.

diamond shipped to Europe
My girlfriend and now fiancee was delighted!!
I ordered a signature round diamond to be shipped to Switzerland. It arrived within the same week, and I was very happy how easy payment and customs procedure was (paid VAT by credit card over the phone). I would not have been able to find this type of quality diamond in the jewelry stores and especially not at this price. The diamond retailers in Switzerland are roughly 30-40% more expensive. I am very happy with my first Blue Nile shopping experience!
