WHAT IS KARAT GOLD?

The quality of karat gold is measured in terms of fractions or percentages of pure or fine gold. Pure gold being 24 of    24 parts or 100% - 1 karat = 1/24 fine gold. No item may be termed "Karat" gold if it is less than 10 Karats of fine gold.

* 10 Karat gold is made up of a blend of 10 parts of pure gold to 14 parts (total 24) of some other metal alloy (or .4167 - 42% pure gold).

* 14 Karat gold is made up of a blend of 14 parts of pure gold to 10 parts (total 24) of some other metal alloy (or .5833 - 58% pure gold).

* 18 Karat gold is made up of a blend of 18 parts of pure gold to 6 parts (total 24) of some other metal alloy (or .7500 - 75% pure gold).

The metal alloy used will determine the color gradients of the karat gold. For example: more copper in the alloy will produce a red or rose color; silver and zinc will produce a green color; nickel, a white color.
