Differences between Karat and Carat

When it comes to jewelry, there are two main terms that you need to be familiar with – karat and carat. While they both have to do with the weight and measurement of precious stones and metals, they mean very different things. In this blog post, we’re going to take a closer look at the differences between karat and carat so that you can be sure you’re getting the right kind of jewelry for your needs.

What is Karat?

Karat is a unit of measure for the purity of gold. Alloys of gold are measured in parts per 24, so 24-karat gold is pure gold, while 18-karat gold is 18 parts gold to 6 parts other metals. The other metals are usually silver and copper. Karat should not be confused with carat, which is a unit of measure for gemstones. Karat is abbreviated as “kt” or “k.” Karats are further subdivided into points. For example, 18-karat gold consists of 18/24 parts or three-fourths pure gold. In the United States, 10 karat gold is the legal minimum purity for an item to be called “gold.” 14 karat is the most popular karat for engagement rings and other jewelry in the United States.

What is Carat?

Carat is a unit of measurement used to determine the weight of gemstones and other small objects. The term is derived from the carob seed, which was historically used as a counterweight when weighing precious stones. One carat equals 0.2 grams and is subdivided into 100 points. Carat weight is the most important factor in determining the value of a diamond and is often used in conjunction with other factors such as clarity and color.

While larger diamonds are rarer and therefore more valuable, Carat weight alone does not determine quality; two diamonds of equal Carat weight can have significantly different values depending on their other qualities. Therefore, it is important to consult with a qualified jeweler to determine the true value of a diamond.

Differences between Karat and Carat

Karat and Carat are two measures of weight often used interchangeably, but they are actually quite different. A karat is a unit of measure used to indicate the purity of gold, with 24 karats being pure gold. Carats, on the other hand, are units used to measure the weight of diamonds and other precious stones. One carat is equal to 200 milligrams. When buying gold or precious stones, it is important to be aware of the difference between karats and carats in order to ensure that you are getting what you expect. Karat is often abbreviated as “kt” while carat is abbreviated as “ct”.
