What Are the Different Types of Gold Colors?

Believe it or not, pure gold, although beautiful, isn’t strong enough to handle the wear and tear of daily life. To make it more durable, it’s typically mixed with other strong alloy metals like palladium and zinc, for instance. Interestingly, these alloy metals, in addition to amping up the metal’s durability, can also change its color. The three main gold colors are as follows:

1. Yellow Gold

Also known as the OG of the gold world, yellow gold is made by mixing pure gold with a bunch of other durable metals like silver, copper and zinc. The result? A metal that’s equal parts strong and beautiful.

What’s more, yellow gold is the closest to pure gold color-wise, making it the go-to choice for those who want to channel their inner Midas without turning everything they touch into, well, gold.

2. White Gold

Created by mixing pure gold with silver, zinc, nickel and/or palladium, white gold is undoubtedly one of the trendiest metals out there. It owes its distinctive sheen to rhodium plating, which basically plays the role of a fairy godmother – turning an already gorgeous metal into something fit for a royal ball.

3. Rose Gold

IMO, rose gold isn’t just a metal; it’s a mood! This blushing beauty gets its pinkish tinge from the copper mixed into the pure gold.

Move over Cupid; rose gold is aiming for your heart!

Gold Purity: What Is It?

The term ‘gold purity’ essentially refers to the amount of gold present within a piece and is measured in karats. The karat scale works by measuring the ratio of pure gold to other alloy metals in an accessory. It ranges from 0 to 24, with 0 karats indicating a gold-free piece and 24 karats indicating that an item is pure gold.

Did You Know?

In the U.S.A., a jewelry piece needs to be at least 10 karats for it to be officially considered gold. So, if you’re planning on treating yourself, aim for double digits darling!

How do I calculate the total percentage of gold within my sparkler, you ask?

Well, you need to do a bit of mathematical cha-cha for that! Take the karat measurement, divide it by 24 and then multiply it by 100. Et voila! You’ve got the magic number that tells you just how pure your gold really is.
