The Facts: 9ct vs 18ct
One of the questions we often get asked is what is the difference between 9ct and 18ct. Below we have explained what the differences are and the pros and cons of these two options.
You may be wondering what exactly the ‘ct’, sometimes seen as ‘K’, refers to. The ‘carat’ of a metal denotes the percentage of pure gold in the alloy, with 9ct being 37.5% and 18ct 75% pure gold. Many come in and ask if it is true that 9ct gold is harder than 18ct gold. This is a misconception.
