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.
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 is better than 14 carat. 24 carat is pure gold. 18 out of 24 is 75% gold the rest is made up of silver.

The 'better' stone would be a combination of its other attributes: colour, cut and clarity, in addition to its carat weight, which you state.
A 14-point stone is 14/100 of a full carat.

18 carat is better than 14 carat. 24 carat is pure gold. 18 out of 24 is 75% gold the rest is made up of silver.
This is the deal on gold: 12 carat = 50% 14 carat = 58.33% 18 carat = 75% 22 carat = 91.67% 23 carat = 95.83 ...
This is very variable; generally between 14 and 18.
The numbers are probably an indication of the purity of the gold. Pure gold is 24 carat but 22 carat, 18 carat, 14 carat and 9 carat are all common.
18 carat gold
75
From its name of 18 carat gold you can tell, if it is truly 18 carat gold, that there is 18/24ths gold and 6/24ths of another metal, possibly copper or platinum. 18 carat gold is (18/24)x100= 75% gold.
different materials are mixed with the gold 18 carat is 75 percent gold
The gold content of 10 karat gold is 41.7% gold. The gold content of 14 karat bold is 58.3% gold.
While 14KT is more durable it is less expensive. 18KT is more valuable but not as durable. Gold is a very weak substance. When alloyed together with different metals it will change its durability. 14KT there is not as much gold which is why it is stronger. 18KT there is more gold which is why it is more valuable.
