The weight of a Diamond or Gemstone
is measured in
CARATS, often abbreviated "ct.".
One carat is 200 milligrams, 5 carats equals 1.00
gram. One carat is divided into 100 parts, called
"points". Therefore, a 25-point Diamond
weighs ¼ or 0.25 of a carat, and a 50-point Diamond
weighs ½ or 0.50 ct.
Diamond and Gemstone weights are usually expressed
in carats and decimals. A 1.09 ct. stone, for example,
would be described as "one o nine carats".
A Diamond that weighs 0.99 ct. is said to weigh "ninety
nine points".
The price per carat of Diamonds will increase with
size; all other factors being equal. Therefore, a
0.50 ct. Diamond will cost more than twice that of
an equal quality 0.25 ct.
While most people would like to own a large Diamond,
it is important to keep in mind that to determine
a Diamonds value, a variety of factors must be taken
into consideration. Cut, clarity, color and carat
weight, not one of them being any more important than
the others, all have to be considered together in
determining the true value of a Diamond.
Large Diamonds and Gemstones are rarer than smaller
Diamonds or Gemstones. The scarcer the Diamond or
Gemstone the greater its worth. So a larger stone
costs more per carat. As you read about the other
THREE of the Four Cs (
Clarity,
Color &
Cut), you will
see how
carat (weight) plays an important role
in Diamond and Gemstone certification.
