Important: pure gold, with a breakdown of 999, is not too suitable for creating jewelry. Such gold is very soft and not persistent before the influence of external factors. Products from it are deformed very quickly. Therefore, jewelers use alloys in which the 79 element of the Mendeleev table is diluted with any other, more durable metal, for example, silver, nickel, cobalt, palladium, zinc.

There are several gold samples. The most used and recognizable are carat and metric.

Important: products and decorations with a breakdown from 999 to 375 are considered golden. But it should be borne in mind that a pure aurum is only 38%in the last, they have the ability to dull in the sun, and they look not quite the same.

Interestingly, jewelry made of white gold is 750 and 585 samples. The product acquires white color due to the presence of silver, nickel or palladium in the alloy, staining it, and rhodium coating.
