It's a given that most people would prefer a large diamond.
However, there are a number of factors that play into how large a stone will appear against how heavy the carat weight might actually be.
As one of the basic 4C's of assessing a diamond, it is important to understand exactly what carat weight entails in order to select the perfect stone.
The higher a diamonds carat, the more valuable it becomes.
Carat refers to the unit of weight used to measure all diamonds. One carat is divided into 100 points (IE. one carat equals 100 points) and each point weighs two milligrams.
Diamond prices do not follow the logic that a 1/2 carat stone will cost half the price of a One Carat stone. This is because finding a one carat stone is far more rare. When weighing jewelry set with multiple stones the total weight of diamonds is referred to as its Total Carat Weight (T.C.W).
The carat weight significantly affects the value of the stone since the cost increases considerably per carat. For example, a 1.00 carat diamond is not exactly half the price of a 2.00 carat diamond. If the weight drops, even by only a few points down to the lower carat weight, the price of the stone will be significantly lowered.
