What is a Enhanced Black Diamond?

Answer:
Usually this means the diamond is natural but not the color -- it was colored to be black. Depending on the process used to color the diamond, the "color enhancement" is either permament regardless of what happens to that diamond or permanent with normal wear and tear (meaning it could lose it's black color in certain sitations - like if subjected to extreme heat).
