A Weighty Matter

Most of the time, people associate carat with size of a diamond, but carat is actually a unit of weight and not a measurement of dimensions. The term carat is derived from the Greek work kerátion which means “fruit of the carob.” In the 1500’s, the middle east starting using carob seeds as a standard of weight for both gemstones and gold. Today, one carat is fixed as a standard weight of 0.20 gram.

These are some common abbreviations for carat:

· CT - You have probably already figured out that ‘ct’ or ‘cts’ is the shortened version of the word carat, as in 0.50ct. It is only used to describe the weight of a single diamond or gemstone.

· TWT - ‘Twt’ is the shortened version of the term carats total weight. For example, if I am referring to a single diamond, I would write 1.25ct, but if I am referring to multiple diamonds, I would write 1.25twt. This means that when I add up the weight of all the diamonds in the jewelry piece, their cumulative weight is 1.25 carats total weight!

So, is bigger always better? I am sure some would argue yes, but as a Graduate Gemologist, I would say not always. Your diamond has to beautiful, first and foremost, and weight of a diamond does not guarantee that. As you may have read in my last three blogs, the proportion of the cut, the color-less, and clearness of a diamond play a big role. You can begin reading my last three blogs for more information at
