A clarity enhanced diamond is a natural diamond, mined from the earth, that has simply been upgraded in clarity.  A great example of a diamond suitable for enhancement would be a diamond that possesses:

Color grades from D - J
An excellent to very good cut
A size of 1 carat or larger

When it comes to diamonds, every woman appreciates a larger stone.   However, when shopping for diamonds, one can find higher clarity graded gems.  Costs can start to add up very quickly for those appearing flawless.  This is where clarity enhanced diamonds shine, especially if you have a set budget, and still want that larger, sparkling beauty on your finger.  All at a much lower price than their natural brethren.
