A word carat contains two meanings connected with jewelry. The article describes the meaning and history of a word carat.

On hearing a word carat the first association we make is a precious gem set in rings. However, it isn't the only meaning of this word. Actually, there are two meanings of the word 'carat'. Firstly, it is a unit of measurement used for precious stones and it is equal to 0.2g. Why this weight and not the other? It is directly connected with history, in the Middle East the stones were weighed by carob seed which weighed 0.2g. The system was reliable enough to become popular in the whole world. The second meaning of the word 'carat' refers to the purity of a gold alloy. Carat measures the amount of pure metal in one unit of its alloy. Till the end of 19th century the measure was given in carats. The calculation was simple, pure gold is 24-carat because it contains 100% of the metal, so one carat amounts to 1/24 unit of gold. The rest of the alloys are described according to the same rule, so 18-carat gold (18*1/24*1000=750). Surprisingly, 585 gold is the most popular in Poland whereas 750 gold and 333 gold are very popular on the markets of the whole world.
