Weight Category (4.04)
One of the 4 Cs, carat, is vital in determining diamond's value. The weight categories thus include valuating the diamond in question. Example: 0.50 carat to 0.69 carat is a weight category. Keep in mind the price per carat will go up as you approach the next higher weight category since it will be a rarer diamond. For example: a 0.99 will be a more sought after and rarer carat weight versus a 0.90 carat even though they are in the same weight category.
