Are the Four C's all you need to know to understand diamonds?

Knowing the Four C's--cut, color, clarity, and carat—is not the end, it’s just the beginning. (One more reason to use an expert.)

"Cut," or the attribute that determines whether or not a diamond will reflect light and sparkle, accounts for 50 percent of a diamond's price.

Paradoxically, however, most grading reports don’t evaluate cut, and the majority of people who sell diamonds don't even understand how cut is assessed.

In addition, other factors, such as surface-reaching breaks and fluorescence, have enormous impact on the price, durability and appearance of your diamond.
