4 Carat Diamonds
A 4 carat diamond of exceptional quality is a very uncommon find. Although carat weights are often spoken in speech, seeing a 4-carat diamond in person is quite amazing. You can get a sense of how valuable a 4-carat diamond is by considering that the average carat weight for an engagement ring in the United States is 1.00ct.
