Carat Vs Karat

Carat and Karat are two words that sound the same but have different meanings and spellings. They are used in jewellery but measure various aspects of precious metals and stones. We aim to clarify the difference between Carat and Karat, including their origins, usage, and commonly confused aspects.

Carat

The unit used to measure the weight of gemstones, especially diamonds is Carat. One Carat is equal to 0.200 grams or 200 milligrams. C or Ct is an abbreviation of Carat. Greek word Keration is the source for the word Carat, meaning "carob seed", used as a standard for weighing small items in ancient times. Carob seeds have a relatively uniform weight of about 0.2 grams, making them a convenient reference point for jewellers.

Karat

Karat is a unit of measure for the purity of gold and other precious metals. One karat is equal to 1/24th part of the pure gold in an alloy. K or Kt is an abbreviation of Karat. The word karat also comes from the Greek word keration. Still, the Romans adopted it to indicate the proportion of gold in a coin. A solidus was a gold coin that weighed 24 keratia, or carob seeds and was pure gold. A siliqua was a silver coin weighing one keratia, 1/24th of a solidus, and equivalent to one karat of gold.

The difference between Carat and karat is vital for consumers and sellers of jewellery, as it affects the value and quality of the items. For gemstones, the carat weight is one factor that determines the price, along with the colour, clarity and cut. Generally, the more the carat weight, the more expensive the gemstone. However, carat weight does not necessarily reflect the size or appearance of the Diamond, as different shapes and cuts may have different densities and proportions.

Gold's Karat purity determines the metal's durability, colour, and value. Generally, the higher the karat purity, the more expensive the gold. However, karat purity does not necessarily reflect the quality or beauty of the gold, as different alloys may have other properties and characteristics. For example, pure gold (24-karat) is very soft and malleable, which makes it unsuitable for jewellery. Most gold jewellery is made from lower-karat alloys added with other precious metals such as silver, copper, zinc, or nickel to increase their strength and hardness. These alloys also affect the colour of the gold, ranging from yellow to white to rose.

One of the common confusions between Carat and Karat is their spelling and pronunciation. In certain countries like the United Kingdom and Australia, the word "carat" is spelt similarly for both meanings. However, they are still pronounced differently (/ˈkærət/ for gemstones and /ˈkɛrət/ for gold). Both words are pronounced the same in other countries, such as the United States and India (/ˈkærət/). It's important to note that the spelling of "carat" for gemstones and "karat" for gold differs. This difference can sometimes lead to confusion and miscommunication when purchasing or selling jewellery online or across borders.

Another area for clarification between Carat and Karat is their usage of other units of measure. Carats are usually divided into points or fractions to give a more precise measurement when measuring gemstones. For instance, a diamond that is half a Carat can be referred to as either 50 points or 0.50 ct. As for gold, Karats are used to show the percentage of gold in an alloy. For example, 18-karat gold may be referred to as either 750 fine or 75% gold.

In conclusion, Carat and karat are two different units of measure for gemstones and gold, respectively. They have different origins, meanings, abbreviations, and implications for jewellery buyers and sellers. They should not be confused or used interchangeably, as they can significantly affect the value and quality of jewellery items.
