Learn how gold purity is measured:
You hear about 14 K, 18 K and 22 K gold, so what is K, and what are the different variations? All K refers to Karat which is a unit of measure for gold purity and denotes how much gold content there is in an alloy relative to the amount of other metals mixed in. If an alloy is 1 karat gold, this means that it contains 1/24th gold, which means that it only contains 1 part of gold and 23 parts of alloyed metal. The 14 K contains 14 parts of gold and 10 parts of alloyed metal, while the 18 K contains 18 parts of gold and 6 parts of alloyed metal. The same process is applied to the 22K, as the 22 K contains 22 parts of gold and only 2 parts of alloyed metal.
Thus, the differences between 14 K, 18 K and 22 K is the gold purity, as such the 24 K gold is the purest gold and the 22 K is purer than 18 K, and surely 18 K is purer than 14 K.

Obtaining a higher grade of K means that you are getting a much more valuable piece of gold.
