Diamond Carat
Diamonds are measured in carats weight not size. The weight of a diamond or carat
size has a substantial influence on the diamonds price. You will find that some
diamonds don't have a good cut so that they can be classed as a higher carat
weight.
The size of a diamond is sometimes determined by what piece of jewellery it will
be used from. 0.75 - 1.00 are popular for earrings, 1.00ct -1.50 are popular for
rings. Some times it’s better to get a smaller diamond with a better cut than a
larger diamond with a poor cut.
