4C’s Diamond Carat

What Does Diamond Carat Measure?

4C’s Diamond Carat – The diamond carat is the weight of the diamond expressed in carats, the official measurement of diamonds. One carat weight is the equivalent of 200 milligrams. To allow for accurate and easy measurement each carat is divided into 100 points. For diamonds less than one carat this allows for diamond to be described by points alone. So a half carat diamond which weighs 0.50 carats may be described as a 50 pointer. Diamonds that weigh in excess of one carat are documented in carats and decimals; e.g. 1.34 carats or 2.51 carats.

Does Size Matter?

In general the price of diamonds increases with diamond carat weight as the larger the diamond the rarer and consequently are more expensive. The majority of recipients of diamond rings would like the largest diamond their budget permits. However, diamond carat is only one of the factors that influence the value and price of a diamond. The other three members of the 4C’s are Cut, Colour and Clarity and these factors significantly affect the value of the stone. If you want a specific carat weight then it may be that you sacrifice some of the other 4C’s to obtain the weight / size you want. This is a personal choice.

Carat Weight, Diamond Value and how it impacts the 4 Cs

Of all the 4C’s carat weight is the only one where a direct comparison is possible. All diamonds weights are measured on a very precise scale designed specifically to weigh extremely small weights. Diamond carat as previously mentioned is a measurement of weight so direct comparison of two or more stones is easily achievable. In general larger stones are more valuable as they are rarer than small ones as the carat weight is higher. However, the scale of the increase is not linear, i.e. a 2 carat diamond is twice the price of a 1 carat diamond. Rather the price difference is exponential to reflect the rarity of the larger stones. Size is definitely not everything as a poorly cut diamond’s value will be significantly reduced when compared to a well cut diamond of the same size. Review 4C’s of Diamond Grading.

What Carat Is and What It Isn’t

Carat is a measurement of a diamond’s weight not an indication of the diamond’s size. With brilliant round diamonds the size of can be roughly estimated as all diamonds have similar proportions. With diamonds of other shapes carat weight is not related to shape and gives a true reflection of the value of the diamond.
