The main difference between 22k and 24k gold, where “K” stands for karat, is their purity. Let’s start with the basics of gold to better understand this.
Gold can be measured in two ways: the first in troy ounces, which measures weight, and then in karats. The higher the karat, the purer the gold is. Having higher purity means that there is more gold content in a piece of jewelry. 24k is the highest level of gold purity—99.99% pure—that can be achieved and purchased. This is also the kind of gold that is the most brilliant yellow in color, sometimes featuring a slightly reddish hue.
When it comes to wearable jewelry, however, 24k gold isn’t always advisable. This is because the purer the gold is, the softer it is. Gold is an incredibly malleable metal, which makes it prone to dents, scratches, and overall breakage. It’s not the strongest metal there is by itself. However, 24k gold still has its uses. It is used for ceremonial pieces—jewelry and other accessories that are worn cautiously and then stored in protected storage for most of their lifespan—as gold bars for investment pieces and in some cases, in medical devices.
To make jewelry (or fashioned jewelry) wearable and durable, expert jewelry makers will alloy (mix) it with other metals such as copper, zinc, or silver. Hence, we get 22k gold, which contains about 91.67% gold and 8.33% of these other metals. 22k gold is preferred by jewelers for everyday wear as it can withstand the natural wear and tear of regular usage. It’s just as beautiful, while coming out stronger. Depending on the alloy, the colors of 22-karat gold can vary. On an additional note, 22k fashioned jewelry is not set with gemstones because it’s still too soft and easily get deformed.
Prices of 24k and 22k gold vary, with 24k being more expensive. Less frequently, 22k gold can be just as expensive if the kind of gold used is certified high-quality.
As a rule of thumb, 18k and 14k gold is the best to invest in when it comes to fashioned jewelry to avoid deformities brought about by wear and tear. There are lower karats available in the market – 12k and 10k, which contain less than 50% of gold – but purchase these with caution. (It’s best to consult a jewelry appraiser.) These lower-karat pieces were likely alloyed with low-quality metals, which increases the chances of the wearer developing an allergic reaction and also decreases durability. Avoid spending more than you should on jewelry like this.
Visit only reputable jewelers who you know use good quality gold and price their items accordingly, focusing your attention on 22k or 18k or 14k pieces if your goal is to add to your collection of everyday, wearable pieces.
