The size of a diamond is measured in carat-weight. One carat is divided into
100 ‘points’, so that a diamond of 75 points, weighs 0.75 of a
carat.
While carat-weight is the most obvious factor when assessing the value of
a diamond, two diamonds of equal size can have very different values, depending
on their respective cut, clarity or colour. Bigger isn't necessarily
better - diamonds of high quality can be found in all size ranges. However,
one diamond of one carat is normally worth more than two diamonds of 0.50ct.
each.
