What is Gold Karat?

Jul 10, 2014

Gold karat
The term "karat" has been used for centuries to as a unit of gold purity. Gold karat is not the same as "carat" which is a measurement of diamond weight. Normally we see 10k, 14k, or 18k jewellery, and naturally the higher you go the more pure the gold is. But what does gold karat really mean? Let's start with 24k gold, which is pure, 100%, real mccoy gold. From now on, think of every piece of gold as having a purity that ranges between 0 and 24. So, if we have a 10k piece of gold, that means 10 parts of 24 is gold, and the other 14 are other alloys. This equates to 41.67% gold and 58.33% of other alloys. Here is a chart that lists out the other purities. gold karat What other alloys are being used to make up the rest of your jewellery? There are an array of alloys that are typically used, such as silver, copper, nickel, zinc, or palladium. Some metals are chosen over others to alter the color. For example, "rose" gold has parts of copper to give that reddish color, and white gold is mixed with a white metal like silver, nickel, or palladium. Obviously the higher the Karat the higher the price of gold you can ask for.
