In fact, gold’s acid resistance is one of the reasons why our acid assays are so accurate.

What happens when you put gold in acid?

How can you tell if gold is pure?

To convert karats into the per centage, you need to divide the karat number by 24 and multiply the result by 100. So, for example, to find out the gold per centage in your 22 karat ring, divide 22 by 24, the result is 0.9166, multiply it with 100, so it equals to 91.66 per cent – that’s the purity of your gold.
