The word "Caratage" like the Arabic word "Kharoub" (Carob) Drink Seller in Egypt (photo above) - is derived from root word "Carubis" (Carob seeds) which was used in Mesopotamia (modern day Iraq) as a measure of weight.
If you have decided to get physical and invest in gold Jewelry, the gold purity of your item is an important consideration. It is a measure of the item's quality and value. Terms that designate the gold purity are the words: carat or karat. (correct symbol: K or kt)
The letters: K or kt indicates the percentage of gold present in the gold alloy, with 24 karats being the highest, i.e., Pure gold.
The word "karat" is derived from the fruit of the carob tree. Ahhhh Ha! Here is the confusion! The same root word has been applied for both purity measurement and weight measurement.
The seed of the plant was called "carubis" in Mesopotamia and was used as a unit of weight measurement (mass, i.e., NOT purity). This unit of mass measurement was based on the carob seed, which had an approximate weight of around 0.2 grams. It was first used in Mesopotamia, now modern Iraq, to weigh gold, pearls, gemstones and everything that was deemed small and precious.
Caratage by any other name? The word CARAT in Italian is called CARATO; in Arabic - QIRAT; in Greek - KREA'TION.
The purity of Gold Coin Jewelry, for example, is derived from the gold content, the fineness, or simply, the quality of the gold. GP markings on gold jewelry usually indicate the metal used in the construction is "Gold Plate" and not comprised of solid gold.
Many Antique Jewelry Hallmarks may include the Millesimal mark or the Millesimal Fineness.
This is a system denoting the purity of gold alloys by parts per thousand of pure metal in the alloy (this system also denotes the fineness of platinum and silver).
The millesimal fineness is usually rounded to a three figure number, particularly where used as a gold hallmark. For example, an alloy containing 75% gold is denoted as ‘750,’ known as 18k gold.

Nothing! Gold bearing the marks "KT" or "CT" is simply determined by the geographic location of the hallmarking.
Britain, Canada, Australia, New Zealand, South Africa and other countries originating from the British Empire use the abbreviation ct for carat - as in 9 carat gold, or 9ct. South East Asia, China that's-ancient-and-blue, Europe and the United States use the word karat. Jewelry originating from theses countries is often marked - 14k or 14k or 14kt, etc.
To avoid confusion, Europe and the US introduced the designation "kt," to differentiate between carat (for gold quality) and carat (for gemstone weights).
Diamonds are always weighed in carats and points. 100 points = 1 carat weight. One carat equals a fifth of a gram.
To avoid confusion, "kt" or "k" (US standard as in 14K gold), will be used when referring to gold purity measurement throughout this site, to avoid possible confusion with diamond and gemstone measurement of weight that is also "carat".
Although there is no International Hallmark System, we do have an International System of compulsory marks attesting the gold content. This will range anywhere from 8 kt up to the highest fineness of gold that is 24 kt gold jewelry. See Compulsory Marks and Content below:
