Qualifying a diamond: The Last of the 4C’s (Carat)


diamonds carat

A one carat diamond is equivalent to 200 milligrams.  In the industry, one carat is also referred to as 100 “points”, the same would apply to 50 points or ½ carat would be designated to a 0.50 carat and so on.

A common misconception is usually that the price of a diamond would double for each doubling of the carat, but this is not the case.  In simpler terms, a 2 or 4 carat diamond does not cost twice or four times as much as a 1 carat diamond.  What does affect the cost is the weight of a diamond, which then the price increases exponentially. This system is created as such because larger diamonds are rarer than smaller diamonds and the fact is that rarity increases the value of a larger diamond.  It is also important to keep in mind that a 2 carat diamond may not look twice the size of a 1 carat diamond when mounted on a ring

Did you ever wonder where the word “carat” comes from?  The term is a derivative of the word carob. Carob seeds were used as a reference for diamond weight in ancient civilizations because of their uniformity in weight.  One carob seed is equivalent to one carat. Here is a link to one of my previous posts about carats but of a different type, the gold type.
