Evaluation:

This is not a great stone at all. It's much too deep, the table is too large, and the thick girdle deceptively increases the carat weight without making the diamond look larger or more beautiful. For $5,500+ you can get much more diamond for your money. Here's an example from Whiteflash.com that goes a lot further for a very similar price.
