A karat signifies how pure gold is and the higher the more gold there is. Pure gold, which is 100%, is too soft to use so it often has other metals mixed in to make more durable. 14 karat gold is about 58.5% pure gold, 18 karat gold means that it has 75.0% gold in it so that means 18k gold is better.

18 carat, of course.

Carat is the term used to express the weight of a diamond, with one carat equaling 200 milligrams of actual weight.

Your spelling of carat confuses the issue.

What you want to know is not about diamond weight -- carats -- but the purity of gold -- karats.

Pure gold is 24 karat: 14 karat means that 10 parts of the mix are something other than gold, usually another, less expensive metal. Eighteen karat means that only six parts of the mix are another metal, which translates into an elevated price for 18 karat gold.

Insofar as use is concerned, 18 karat gold is a little softer than 14 karat gold, so if the jewelery is worn continuously, the 18 karat gold piece is likely to show wear before the 14 karat gold piece will show it.
