You can also convert this karat value into per centage with above-mentioned formula. It should come to 75 per cent gold content. Here are some of the frequently used karat marks and their corresponding percentages with respective parts-per-thousand values: 24K — This comes out to be 0. Today, we commonly encounter both carat and karat in reference to fine jewelry, where size and quality are emphasized, with carat usually designating the size of a stone and karat designating the proportion of gold in an alloy.

Many of us, at one point or another, will shop for gold in the jewelry department of a department store or in a jewelry store. The higher the karat, the more expensive it will be. But have you ever wondered why? What does it all mean? And what is all of that fine print stamped into your piece of gold? What are karats really? How do you know how pure that gold really is? This article will answer these questions and more. Karats, spelled "carats" outside of North America, are the little numbers stamped on a piece of gold in the format of "xxK" or "xxKT".
The numbers refer to the type of gold and to the actual gold content in the particular piece of jewelry. Gold is malleable in its pure state. Other metals are added to strengthen it and in some cases to enhance color. An example is "rose gold" comprises gold and copper. Knowing the number of karats is key to calculating the gold content on your own.

Purer gold does not mean better, it means more pure, worth more money, and more expensive. As stated earlier, the less pure the gold is, the more alloy metals it contains. Gold that is blended with more alloys is stronger. This may be preferable especially for jewelry as 24K gold is very soft and not as durable.
The lower the karats in a ring, the stronger it will be. Choose the purity level that makes the most sense for what you intend to use it for, whether you will subject it to a lot of force, and your personal preferences. Gold is very flexible and is used in many industries for various purposes, depending on the purity.
Many industries use gold for jewelry-making all the way to food applications.
