Larger stones are discovered less frequently than smaller stones and their rarity is reflected in the diamond’s “per carat” price. Due to the rarity of larger stones, the price per carat increases as the size of the stone increases. For example, a 2 carat stone is more expensive than two 1 carat stones because the price per carat of a 2 carat stone is much higher than that of a 1 carat stone.
