I'm not sure what you mean by find pure gold from an already made 18 crt ornament, but if you want to know the percentage of gold it is 18/24 which is .75. So something that is 18 crt. is 75% pure gold and 25% not gold.

That will be more time involved for the difference in money you will receive. Depending upon which method you want to use, you can die trying.

The jewelry might have to be dissolved in an acid first, though
