Buying a diamond, especially a diamond engagement ring or loose stones intended for an engagement ring is a very
special moment in your life. However as
it is an investment, you want to be sure you know what you are buying. Diamonds are sold by carat weight and the
larger the carat weight, the rarer and more valuable the diamond is likely to
be.
The word carat is derived from the
word carob and was the original unit of measure for diamond traders. The Mediterranean carob seed was an extremely
consistent weight of measurement. The abbreviation for carat is “ct.” and a
metric “carat” is defined as 200 milligrams or 1/5 of a gram. The metric carat weight was standardized in
the 20th century and the U.S. officially adopted the measurement in
1913.
The GIA explains that “each carat can
be subdivided into 100 points,” which means that every stone has a very precise
measurement to the hundredth decimal place. From a jeweler’s perspective, this means they
may describe the weight of a diamond under one carat by the ‘points’ alone. For example if a diamond weighs 0.25 carats, a
jeweler may describe the stone as a ‘twenty-five pointer.’ The GIA notes that “diamond weights greater
than one carat are expressed in carats and decimals. A 1.08 carat stone would
be described as ‘one point oh eight carats.”
When shopping for a diamond, please
remember that a diamond’s value is not just based on the carat weight. This means that any two diamonds of equal
carat weight will not necessarily cost the same. Diamonds are also valued based on three
other factors - Clarity, Color, and Cut.
