A carat is the standard measure of a diamond’s weight. There are 100 points in one carat, so a 1.5 carat diamond can also be described as a stone of 150 points.

Size alone does not determine the value of a diamond because the color, clarity and cut of the stone are so important. For this reason high-quality smaller stones can be more valuable than lesser quality larger stones.

However, in comparing stones of similar quality, the larger a stone, the rarer it is, and the more value it has.
