14 karat gold refers to an alloy gold in which content of pure gold by weight is 14 parts out of 24 parts.

24 carat gold has 24 parts out of 24 parts gold - that is, it is 100% pure gold.

Similarly 12 carat gold will have 50% pure gold and 50% other metals. 18 carat gold will have 75% pure gold and 25% other metals.

Of course we cannot have more than 24 carat gold.

Hondadrx-

As you probably already know, karat measures the purity of gold alloy.

When measuring a purity of gold alloy, one karat is 1/24 purity by mass.  This means that 1 karat would equal approximate 4.2% purity.

As for answering your question, 14 karat would mean that the gold alloy you possess would have approximately 58.5% purity while the 24 karat gold alloy would have 99.9% purity.

Thus, 24 karat would be considered to be pure gold.
