The karats of gold are Quite simply, values that indicate the degree of purity of gold from impurities and are measured in carats, and for a more accurate and clearer knowledge, we must address the term carat itself. The carat, which has several ways of pronunciation, is derived from the English word “Carat” and is engraved on the gold piece with the following pattern “xxK” or “xxKT”, as the last letter in the first symbol and the last two letters in the second symbol are an abbreviation of the word karat, While the letter “x” refers to the numbers that determine the degree of purity of gold. The degree of purity of gold is the ratio of the actual gold metal to other metals in the ingot or piece of gold, as gold is one of the metals that exist in its pure form in nature and is symbolized by the symbol “Au”. To give an example for simplicity, oil or “gasoline” It is classified according to its degree of purity into categories, gasoline 2019 And416, the same applies to gold.
Gold karats are determined on a scale from 0 to 24.
The higher the gold carat, the higher the degree of its purity, and therefore its value and price in relation to other carats.
The highest calibers of gold consist of pure gold in a manner higher compared to impurities such as iron, aluminum, copper, nickel, and sometimes silver and palladium. *) Based on the scale of degrees of gold, gold is caliber 58 It is the purest gold that can be purchased because its purity is the highest.
In some cases other metals are added To gold in order to strengthen it because gold is a somewhat malleable metal in its pure form or to change its color, for example to a pink color that is determined by adding the element copper to pure gold.

Based on this basis, the equation used is:
“The highest value of the carat is fixed” / X “ A variable representing the value of the carat to be known as the percentage of pure gold to its impurities” = the percentage of pure gold.
