How Is Gold Purity Measured?

How is Gold’s purity measured?

The answer to this is it’s Caratage. The weight of gold is measured in troy ounces (1 troy ounce = 31.1034768 grams), however its purity is measured in 'carats'. 'Caratage' is the measurement of purity of gold alloyed with other metals. Other metals and alloys could include copper, nickel (not common anymore), silver, or palladium.

Karats are measured on a scale from 0 to 24.

24k gold is all parts gold without traces of other metals. Because of this, it has a uniquely rich, bright yellow hue. This pureness and rare color makes 24k gold highly desirable, the most expensive, and most often used in fine jewelry. Below is a chart showing the different purity’s.

So why would other metals be added to pure gold?

Gold is very malleable in its pure state. Other metals are added to strengthen it and, in some cases, to enhance color. An example is "rose gold" comprised of gold and copper.

When it comes to purity, in some instances it may be more reasonable to have a lower carat gold, such as a ring that you would want to be stronger and not as flexible. But, when collecting bullion, it is always best to have the purest gold being 24KT (999,9 Fine Gold).

While 999 means that your gold is 99.90% pure and only 0.1% is other metal, 999.9 means your gold is 99.99% pure (24KT). It is important to note that with bullion, there are many different shapes and sizes that your gold bullion may come in but it should always have the weight and purity right on the piece itself for you to be comfortable in the amount and purity of gold you are receiving!
