The diamond carat size is the unit of measurement used to indicate the weight of a diamond. Since 1913 diamond carat weight has been measured compared to the metric system with one carat equaling 200 milligrams. The weight of a diamond is measured up to three decimals and rounded to the nearest hundred.
There is no linear link between the weight of the diamond (carat) and the value of the diamond. Most rough diamonds that are mined are either too small or have an inferior quality to produce diamonds that are used in the jewelry market. It can take up to one million rough diamonds to produce one single one-carat diamond.
Due to the rarity of larger diamonds a one-carat diamond can often by 4 to 6 times the price of a half carat diamond.
Carat weight will be one of the most important factors that determine the price of your diamond. Below we listed some tips to consider when choosing which carat weight is right for you:
