Hi Vallie T. Mcninch:
I'm not an expert on diamonds, but I did talk to a few when doing research for Jewel Heist.
Here is some information that might help you.
What Is Diamond Clarity?>>
Diamond clarity is a term used to describe the absence or presence of flaws inside or on the surface of a diamond or other gemstone. A perfect stone with perfect clarity, or clearness, is rare, and most flaws that do exist in jewelry grade diamonds cannot be seen without looking at the gems through a jeweler's magnifying loupe. http://jewelry.about.com/cs/diamondc...ge_clarity.htm>>
