Carat is the most visible C. People often think it refers to the size of the diamond, but it actually refers to the weight. The larger the diamond, the rarer and more valuable it becomes. But to truly understand the diamond’s size, you need to evaluate the measurements.
The size of a diamond is measured in millimeters by length and width, or in its diameter.
1.00 carats = 0.20 grams ( ⅕ gr)
5.00 ct = 1.00 gr
100 points = 1 cts
0.50 ct = 50 points
0.25 ct = 25 points
