About gold karat identification symbol mark stamp.
I have a gold chain that has the number 417 on the
What does 417 mean?
Stampings like these on Gold
are in reference to the alloy mixture of the piece of jewelry or "Karat"
of the Gold. In everyday terms we are used to referring to gold as 14
karat or 10 karat and so on. The number 417 gives a more accurate
indication of what the alloy consist of. Gold will range from 1 karat
to 24 karat with 24 karat being 99.99% pure gold. Therefore you can
determine the amount of pure Gold in a piece by dividing the karat by
24. For example if we have a 10 karat gold chain, 10/24 = .41666 or
simply put for stamping purposes 417. Or the opposite if we have a piece
stamped 584, then .584*24 = 14.016 or 14 karat.
It is a common practice to round these numbers for the
purpose of making it easier to stamp them on smaller pieces or as to not
take away from the glamour of the piece.
