is 'Carat' ? |
Answer : |
|
In the Troy weight, which is used by jewellers in weighing precious metals and stones, a Carat is equal to 3.168 grains.
|
| The
term Carat is a variation of Carat and in form is used in comparing
the parts of gold alloys which are in gold. |
|
Abbreviation : ct or Kt

|
The word carat is derived from the Greek kerátio-n, fruit of the carob, via Arabic qi-ra-t and Italian.

The comparison is based on the use of 24 Carats to mean pure
gold, and therefore 14 Carats to mean 14/24 pure gold by weight
or 14 parts pure gold and 10 parts alloy. |
