The 4Cs of Diamonds: What is Diamond Carat Weight?

Understanding Diamond Carat Weight

Carat is the unit of measurement for the physical weight of diamonds. One carat equals 0.200 grams or 1/5 gram and is subdivided into 100 points. For comparison, in units more familiar in the United States, one carat equals 0.007 ounce avoirdupois. Which would require over 2,265 carats to equal 1 pound!

How Carat Weight Plays Into the 4 Cs and Diamond Value

Carat weight is the most objective of the diamond’s 4Cs. All that is required is a precisely balanced scale capable of measuring extremely small weights.

Here are some facts about a diamond’s weight and price that are important to understand before purchasing.

Comparing the value of diamonds by carat weight is like comparing the value of paintings by size. Large diamonds are rarer than smaller ones, and as the carat weight increases, the value of the diamond increases as well. However, the increase in value is not proportionate to the size increase.

For example, a 1-carat diamond will cost more than twice that of a ½-carat diamond (assuming Color, Clarity and Cut grade are the same). Weight does not always enhance the value of a diamond, either. Two diamonds of equal weight may be unequal in value, depending upon other determining factors such as Cut, Color and Clarity. In fact, if a diamond is improperly cut, the added weight may serve only to reduce its brilliance.

…to Summarise

Diamond carat weight measures how much a diamond weighs. While you now understand what carat weight is, it’s also important to remember that a diamond’s value is determined using all of the 4Cs, and not just carat weight.

It is always wise to consult and take advice from a professional jeweller. It would help you better understand your choices and shape your buying decision in getting the right diamond.
