UNDERSTANDING
GOLD KARATS

Not all gold is created equal. Learn more about the karat system and how to choose gold jewelry that reflects your inner glow.

WHAT DOES KARAT MEAN?

If you’ve ever shopped for gold jewelry, you’ve probably heard the word ‘karat’; if you’ve ever shopped for diamonds, you’ve probably come across the word ‘carat’. While they are pronounced the same, carat refers to one of the 4Cs used to determine the value of a diamond, and karat is used exclusively for gold.

CHOOSING THE RIGHT KARAT

Understanding what the most common gold karats mean and how it affects price, quality and value is the key to finding a piece of gold jewelry that works for you. When it comes to jewelry, quality and value don’t necessarily go hand in hand. While 24K gold is the purest and most valuable, it isn’t the best choice if you want a quality piece of gold jewelry you can actually wear—and that’s the whole point, right?

Here’s what you should know about karats to make the best choice for you:

24K

The purest and most valuable gold available.

Gold mined directly from the earth is 24K, but it’s rarely used in jewelry in this form because it’s much too soft and easily damaged to be practical.

24K gold will be combined with other metals to create a more durable alloy.

18K

Made up of 75% gold and 25% other metals or 18 out of 24 parts gold, 18K gold has the highest ratio of pure gold vs. other metals. While it is more durable than 24K gold, 18K can still be vulnerable to scratches and can damage more easily.

Also, thanks to its purity, 18K is on the more expensive end of the spectrum.

While it is highly valuable and technically durable enough for jewelry, a lower karat might actually be more practical.

14K

Made up of 58.3% gold and 41.7% alloy, or 14 out of 24 parts gold.

For jewelry that is worn every day, such as engagement rings and wedding rings, 14K gold is the most popular choice. It’s also common for earrings and body jewelry since 14K or higher is recommended for all types of piercings.

A bit more affordable than higher karat forms, 14K is more resistant to scratches and damage and can be easily resized.

10K

Made up of 41.7% gold and 58.3 alloy or 10 out of 24 parts gold.

10K gold is the least pure, least expensive, but most durable form of gold used in jewelry making it a good choice for all types of jewelry from everyday hoops and stud earrings to bracelets and necklaces. It’s also an accessible option for anyone who wants genuine gold but is shopping on a budget.

One thing to keep in mind is that 10K can contain metals such as nickel or copper that may cause an allergic reaction for some.

HOW TO TELL IF GOLD IS REAL

From 10K to 24K, all forms of gold are considered “real” gold because they all contain a percentage of gold in its purest form in addition to other metals. That being said, there are other metals that can look like gold at first glance so it’s important to make sure your jewelry actually contains karat gold.

WHITE GOLD & ROSE GOLD

When gold is mined from the earth, it has the signature yellow color you associate with gold. White gold and rose gold are not natural metals, so while they are still considered “real” gold, they don’t come in 24K. Instead, white gold and rose gold are specific alloys that give them their unique color.

White gold is an alloy containing a mix of palladium, platinum, and silver. It’s also always coated in rhodium to eliminate any yellow sheen that is lingering from the gold. Rhodium gives white gold its pure white gleam and a little added strength to protect the soft metal underneath.

Rose gold is an alloy of silver and copper that is less prone to damage than white or yellow gold thanks to the durability the other metals add. It’s also less prone to tarnish and doesn’t require a coating to maintain its pink color.
