A carat is the unit of measurement used to weigh diamonds and
other gemstones. One carat is equal to 200 milligrams, or 0.2 grams
and is usually written as ct.
All diamonds on the diamonds.co.nz database are weighed
to three decimal places for accuracy, for example 1.028 ct.
The word carat is derived from the seed from the fruit of the
carob tree. The seeds are relatively uniform in weight and were
once used throughout the Mediterranean basin as counterweights
in simple balances. The word carat is supposedly derived from keration,
the Greek name for the tree.
When you think about carat weight you should also think about millimeter
size and diameters. The following diagram shows the relative size
of various carat weights in a round brilliant cut diamond that
