great piece, very versatile, and exceptional value. good quality diamonds and the chain is thin but doesn't grab your hair as others i own. I won't buy my jewelry in Dep. Stores anymore. Thanks

She loved it - and she can be picky!

I am very satisfied with this pendant, sparkling and colorless. My husband and I went to local stores to shop for the ideal diamond necklace for our 10 year anniversary, but compared with the quality and price to pay, we decided to try BlueNile. It was a wise decision. The cut of the diamond is terrific which enables the diamond to reflect most light back to the eye instead of going through the diamond. I am also very pleased with the service from BlueNile. Shipping was quick and safe. I would highly recommend this necklace to my friends.

As usual Blue Nile comes through with quality as described. Very happy with all my purchases. Will be back again soon I'm sure.
