In order to measure the purity of gold, it is mixed with an alloy to form the final metal which is used as a carat and its international symbol is Kt or K.

In jewelry of 14 carats purity, the repartition of gold in the alloy is 58, 5% (585 for every 1000 parts) and the compulsory stamp that the jewel should bare is either 14K or 585. In jewelry of 18 carats, gold repartition in the alloy is 75% (750 per 1000 parts) and the compulsory stamp that the jewel should bare is either Κ18 or 750. The final value of the jewel is determined by its weight, its processing and the value of the gems it contains. The higher the proportion of gold used to form the final metal, the higher and more expensive the metal. Thus, if all other elements that determine the value of the metal remain the same (gemstones, process), an 18Kt jewel it is expected to be more expensive than an 14Kt jewel.
