Carat Gold which is often misspelled for Karat Gold or K Gold Price when it comes to referring to precious metals that is.
The word carat gets its roots in the Greek nom kerátion and Italian carato. Carob grains were made to serve as as balance to weigh on fine precision scales since their reputation to being a constant and consistent uniform weight-size. But, a 2006 study uncovered this not to be the case – carob grains do have as much difference and variance in their weight-sizes as other grains-seeds. It is reported in order to keep regional sellers and buyers of silver, gold and precious metals honest, eventual clients could retrieve their own grains on their way to the market, to check the tolerances of the grains-seeds that the sellers were using.
Now Carat Gold would be correctly said to Karat Gold. Carat Diamond on the other hand is correct.
Carat or Karat for gold purity is measured as in 24 x the purity in by its mass.
Therefore, 24 Karat gold is fine (ninety nine percent), 18 Karat gold is seventy five percent gold, 12 Karat gold is then fifty percent gold, and so on.
The carat / karat measurement approach is increasingly complemented or superseded by the millesimal fineness approach, in which the purity of precious metals is defined in parts per thousand of pure precious metal in the alloy.
Most common measurements are:
- 24 carat gold (millesimal fineness 999 or higher) = 24 Karat gold, 24 K Gold
- 22 carat gold (millesimal fineness 916) = 24 Karat gold, 22 K Gold
- 21 carat gold(millesimal fineness 875) = 22 Karat gold, 21 K Gold
- 20 carat gold (millesimal fineness 833) = 20 Karat gold, 20 K Gold
- 18 carat gold (millesimal fineness 750) = 18 Karat gold, 18 K Gold
- 15 carat gold (millesimal fineness 625) = 15 Karat gold, 15 K Gold
- 14 carat gold (millesimal fineness 585) = 14 Karat gold, 14 K Gold
- 10 carat gold (millesimal fineness 417) = 10 Karat gold, 10 K Gold
