What are Diamond Karats?

Video Transcript

In this segment we are talking about measuring and how to measure and where measuring was derived. Originally the karat bean was used to weight or to measure a diamond and obtain its weight. The karat bean is an actual bean that grows in the forests of Africa and it was a bean that was used to rate a diamond that was found from the Earth and from that point if you had five karat beans you had five karats of stones regardless of how big they were. The karat bean would give you how much those stones would weigh. We have passed through time an different methods of how to measure karating and we have electronic devices which are scales that have specified weights that we can use to measure diamonds and we also have scales that counterbalance and that you can put weights on one side and diamonds on the other which is the closest form of the karat bean story and you go further down on the line and to get very technical especially when you are appraising or evaluating stones and you have what is called the leverage system. You have an instrument here that measures a diamond by its length and its width and its depth and you can also use a chart and relate to that stone and identify it by weight within two to three points. Determining the girdle thickness on the center of this stone and culet factors, all of these things are determining factors when you evaluate proper weight.
