- This word is often confused with "karat", a completely different term used to describe
the quality of gold.
- Since all diamonds must be cut and polished to remove the outer layer of "rough",
large diamonds are rare.
- The price of diamonds rises as their size and weight increase. Therefore, a two
carat diamond can cost four times as much as a one carat diamond of the same quality.
- Some gemologists describe diamond weight in terms of points, not carats. 1 carat
= 100 points • 1/2 carat = 50 points • 1/4 carat = 25 points • etc.
