The Difference Between a Karat and a Carat

More Than Just a Letter

It’s pretty interesting how switching a single letter can entirely alter the meaning of a word! Some people think that these two homonyms are just different ways of spelling the same thing. Carat or karat, which is correct? They actually don’t even refer to the same measurement! There’s a major difference between carat and karat that goes beyond the spelling. In order to compare carat vs. karat, we must understand the application of each word and their relationship with their respective raw materials. 

The term “carat” applies to diamonds and is considered one of the 4 C’s used to measure diamond quality (carat, color, clarity and cut). Early in the 20th century, diamond distributors agreed upon a set weight to measure the size of a standard diamond. A one carat diamond was settled to be equivalent to 200 milligrams, or 0.2 grams of finished weight.

Karatage, on the other hand, refers to the purity of gold and is measured on a scale made up of 24 parts. 24 karats of gold indicates that 24 of 24 parts of the metal mixture are gold, or in other words, 100% pure gold. Most standard karatages of gold used in fine jewelry range from 10k gold to 24k gold.

In simple terms, carats refer to diamond weight, whereas karats refer to the purity of gold. Being aware of these differences is helpful in understanding what you’re buying in the jewelry realm. This knowledge is especially important when looking to buy gold jewelry online without the direct advice of an expert jeweler. 

The Perfect Blend

Without much understanding of metal alloys, it would be simple to assume that the best jewelry available would be whichever one has the highest purity of gold. Things aren’t always as simple as they seem, though. Despite 24K gold being completely pure, it’s very rarely used in its natural form. This is because gold is a naturally soft metal, which easily falls apart with the slightest amount of friction. If you were to wear 24K gold on a daily basis, the gold particles would slowly flake off until there’s next to nothing left. For this reason, most high-end jewelry is crafted from a maximum of 20K gold. This mixture is 83.3% gold, plus other metals such as copper, zinc, silver, and nickel (depending on whether the final product is yellow, rose or white in coloration). Vintage jewelry used to be made of 21K gold, which is slightly higher in gold, but has since fallen out of fashion.

In addition to being responsible for color, the other metal alloys create durability and a higher resistance to scratches or dents. 18K gold is a very popular blend since it’s very resistant to damage while still retaining natural gold’s deep, warm yellow hue. 14K gold and 10K gold are more budget-friendly options, since less gold is used to create these mixtures. These lesser karatages are great choices for your everyday casual wear, especially if you live an active lifestyle, as they are both cost-effective and the most resistant to damages that may result from normal use. For all the reasons listed above, the ideal karatage of gold for your specific piece of jewelry should be chosen based on budget, lifestyle and desired coloration. 24K gold isn’t simply the best fit for every accessory. 

Carats With A “C”

They don’t call diamonds precious stones without reason. A diamond takes millions of years to form. They also take several years to mine and are very rare amid the tones of rock that surrounds them. Diamond price doesn’t necessarily increase with a diamond’s size on a linear scale. Larger diamonds are actually exponentially more expensive. That’s because it’s even more extraordinary to find diamonds that weigh more than a carat.

Conditions have to be just right for a very long time to allow the pressure deep within the Earth’s surface to form layer upon layer of perfect, clear minerals. Furthermore, it’s very unlikely that these big diamonds end up being flawless. All these nuances of diamond formations result in incredibly high sales prices for really big, really high quality stones. The stones used as centerpieces of engagement rings have historically averaged slightly more than a carat and that average is decreasing over time. The advantage of a smaller diamond is that the flaws are less visible, so you can afford to buy a lower clarity while still maintaining a flawless appearance.

What Is The Difference Between Carat and Karat?
