18 karat
There is more gold in 18 karat gold (approx 70%) than in 14 karat gold (only 50% gold) making 18 karat gold more valuable. However gold is a soft metal so the higher the gold content the less durable the jewelery. Therefore depending on the use one may prefer 14 karat gold, for something like a chain that needs to be more durable than say earrings.
Just the opposite, actually. On a 24 point purity scale, 18 is more pure than 14.
What purity of gold is it? (ex: 14 karat? 18 karat?)
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.Another AnswerYour 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.

14 Karat gold is more expensive, so to some it might be considered "better", but 10 Karat gold is more durable, so will scratch/bend less and could possibly last longer.
