What is gold rate?
"Ayar" refers to the degree of purity of gold in artifacts made of gold. Gold carat is calculated from the complete unit of 24. For example, 24 karat gold is pure gold with at least 99.9% gold. Or, for example, 18 carat gold is composed of 75% gold and 25% other metals. Rather, it determines the amount of other metals that are used in making gold artifacts. Generally, different numbers such as 18K, 14K or 10K are used to determine the grade. Each of these numbers indicates the presence of a certain percentage of gold in an object. The English letter K next to these numbers is the first letter of the word karat. Carats are used to show the purity percentage of gold. Of course, you should note that in English "carat" is called "karat" (carat or Karat) and for this reason it is specified with the abbreviation K. But this carat is different from the carat, which is the unit of measurement for the mass of precious stones and pearls.
So we found out that "carat" is the unit for measuring the purity of gold alloys and other precious metals. You probably have a question, why do they combine gold with other metals? This is because pure gold is inherently soft and may change shape when used in making artefacts. Therefore, in order to have sufficient hardness and strength, it is usually combined with other metals such as copper, silver, platinum and nickel.
What is the difference between gold carats and which one is the best?
24 karat gold (24K): is a pure gold and no other metal is used in it.
18 karat gold (18K):< /b> consists of 18 units of gold and 6 units of other metals (copper, silver or platinum). It means that the purity of its gold is 75%.
14 karat gold (14K): It consists of 14 units of gold and 10 units of other metals. This means that the purity of its gold is 58.3%.
First point: You should note that these codes that are written on gold are also called "stamps". which has the same concept as carat. Second point: precious metals such as gold and silver are sometimes carated with 1000 units. For example, 750 carat gold is equivalent to 18 carat. It means that 750 units out of 1000 units of gold artefacts are made of pure gold and the rest is an alloy of other metals.
What is the difference between 18 carat and 24 carat gold?
18 karat gold is the best form of gold in terms of resistance and purity. In fact, 18 gold means that 18 units out of 24 units of a piece of gold are made of this precious metal and the other 6 units are made of other metals. 18-carat gold has 75% pure gold. 24-carat gold is completely yellow and shiny and is the purest type of gold that can be used in the jewelry industry. Which carat of gold artifacts is better than that one cannot be given a single answer. Because in different countries of the world, which have accepted different carats as standards. For example, in Iran, 18-karat gold, 21-karat gold in Saudi Arabia, and 24-karat gold in the countries of the Indian subcontinent are official standards.
