Diamonds have been totalled in Carat Weight.
One carat weighs 200 milligrams. If a
diamond is referred to as 4 grains, this
also equates to which it is a a single carat diamond.
The word Carat comes from a word carob.
A carob is a bean which grows upon a tree in the
Mediterranean. In times past, if a diamond
weighed a same as a carob bean, it was
one carob, or a single carat.
However, in a distant east, where Carob trees
do not grow, rice was used to magnitude the
weight of a diamond. If a solid weighed
as most as 4 grains of rice, it was four
grains – or a single carat as we know it to be
now. The infancy of solid purchases
are for diamonds which have been 1/3 of a carat.
Beware when selling for diamonds that
are already set or mounted. If some-more than one
diamond is used in a piece, a tab upon the
jewelry will give a CTW or Carat Total
Weight – it does not discuss it we a carat weight
of any mill in a piece. You need to ask
the jeweler for a sum carat weight of the
largest solid in a square to truly
understand what we have been buying.
