Carat not caret . I am a gemologists and have been weighing diamonds for over 30 years. The term ‘carat’ is a derivative of the word carob. Carob seeds are surprisingly similar in weight to one another; thus they were used in ancient times as the standard of weight to measure diamonds, as well as other precious stones. One carob seed equaled the weight of a one carat diamond. Thus the term is still used today . And the abbreviation is ct. not kt. kt. refers to gold purity such as 14kt.
