Most people compare carat weight to size. The larger the diamond
the more it weighs. The weight of a diamond is expressed in
carats. The word carat originated from the carob tree or Ceratonia
siliqua. The tiny seeds of this tree are well known for their
uniformity and consistent weight. Traditionally diamonds and
gemstones were weighed against these seeds until the system
was standardized, and one carat was fixed at 0.2 grams. One
carat is divided into 100 points. A diamond weighing one quarter
of a carat can also be described as weighing 25 points or
0.25 carats. Points are generally not used to describe weights
over one carat.
A diamond’s beauty, rarity, and price depend on
the interplay of all the 4Cs - cut, clarity, carat, and color.
