Carat Weight

The cost of diamonds is proportional to the carat. Typically the diamonds with a higher carat value fetch a higher price than that of a lower carat value.

The size or weight of a diamond is measured in carats (ct.). A carat is 0.2 grams and each carat consists of 100 points (or 200 milligrams). Having an accuracy of 1/100,000 ct, the IGI. scales give an extremely precise diamond weight. The Diamond report contains this weight upto two decimal places.

Going by the guideline, the cost per carat increases as we progress from smaller to larger stones. This is due to the fact that the larger stones are very much limited in supply. Consider an example of two stones of the same quality, one weighing ½ carat & the other weighing ¼ carat. Thought the two stones have the same quality, the one weighing ½ carat will cost more that the one weighing ¼ carat.
