In most cases if not all,
Most native metallic gold runs from 18K to 20K (75%-85%).usually lower, even less than 12K, or 50% gold.
but it can have a higher or much lower purity since it is mixed with the rock and dirt where it is found.
These are usually silver and copper, but can include nickel, platinum metals and a host of others leached from the ore and added to the gold in processing.

22K gold contains 91.7% gold.
At most we generally refine gold to 99.999% pure. This 99.999 % pure gold is what is known and categorized as 24K gold.
When you are buying a 24K gold coin/bar, always look for a hallmark certification to ensure its purity.
It is better to buy gold from a BIS hallmarked jeweller so that you get prevalent value of gold when you sell it.
