Diamond Basics
Carat Weight: Size, Price and Value
One carat equals 0.2 grams. Price rises sharply at popular 'magic' weights such as 1.00 ct.
Carat is weight, not size
Two 1-carat diamonds can look different in size depending on cut depth. Check millimetre measurements on the report, not just weight.
Buying just under
A 0.90 ct diamond can cost 15–25% less than a 1.00 ct and look virtually identical once set.
