DIAMOND WEIGHT:
The weight of diamonds is measured in carats (abbreviation ct) (not to be confused with gold purity). One carat equals 0.2 grams. The name comes from the name of the seeds of sweet carob (Ceratonia siliqua, Carob). In ancient times, these seeds were used as weights, and their weight is very close, on average 0.2 g. Natural diamonds vary in size. Among the thousands of tiny grains, there are quite large crystals weighing hundreds or even thousands of carats. As the number of carats increases, the price of the diamond increases proportionally, because each diamond is cut from one piece of crystal. To get a larger diamond, the crystal must also be larger. Large crystals are extremely rare. Sometimes large crystals have to be cut into more pieces, resulting in smaller but better quality diamonds (higher brilliance and clarity). Therefore, 1 ct. a diamond can cost significantly more than 0.9 ct. diamond.
