More on the Karat
It is a common misconception that a karat is a unit of weight but it is actually a unit of measurement for the amount of gold contained within an item.
“Karat” is also different from “carat,” which is a metric unit of weight for gemstones.
Karat (or kt) indicates how many percentage of pure gold is alloyed with other metals like silver, copper, zinc and so on.
Pure gold (99.99%) is generally considered to be too soft and pricey for daily enjoyment.
For this reason, it has to be mixed with other alloys to maximize its strength and at the same time, price can be lowered down as it contains inexpensive materials to target larger consumptions.
Only 24 karat is known as 99.99% pure gold.
18kt gold has approximately 75% of pure gold and stamped either “18kt” or “750” for European marking standard.
Likewise, 14kt gold has approx. 58.5% of pure gold and stamped “14kt” or “585” for European marking standard.14kt gold is most commonly used in US.
Finally, 10kt gold has approx. 41.7% of pure gold and stamped “10KT” or “417” for European marking standard.
