This is such a kewl stone from so many standpoints!

First, let's look at the color....

Gray - whiich is generally a dull color. Yet, it's really got life and sparkle.

In spite of the fact that its clarity is sometimes referred to as "salt and pepper". It's got a bunch of small black carbon spots and a couple of white ones. However, it still manages to sparkle!

Last, and by no means least is the cut... it's a " Moval" and it's really a well done moval at that.

Large bright flashes from this unlikely specimen. Very cool diamond.
