Diamond Carat

The weight or size of a diamond is measured in carats. A one-carat stone is equal in weight to one hundred smaller units called points. Carat weight is the most obvious factor in determining a diamond's value, dependending on the quality of its cut, clarity and color. Be aware that the price of a stone may jump after certain weight thresholds (usually at quarter-carat marks, such as 25 or 75 points).

Approximate sizes as measured in milimeters:

 

To gauge the trade-offs of differing values of the 4Cs, when comparing diamonds of similar qualities always convert the price to "price per carat". To convert the price, simply divide the "total price" by the carat weight of the diamond. For example,

Diamond Specifications: Total Price Price Per Carat
1.10 ct., G, VS2 $6,200 $5,636 (6200/1.10)
1.25 ct., G, VS2 $6,400 $5,120
1.15 ct., H, VS1 $6,000 $5,217

The are literally thousands of combinations of diamond size, color, clarity, and cut possibilities, with a mulitude of trade-offs. Level the playing field by always comparing the price per carat and determine the quality trade-offs you are willing to accept. Always consult a trusted jeweler.
