How much is a bracelet that is gold and silver worth that has 925 PAJ china stamped on it?

The only thing that "925" tells you is the fineness of the metal that the bracelet is made of. Fineness is a way of expressing the fraction of pure precious metal in an item. Normally it's shown as 3 digits, in which case it means that portion out of 1000. (Some items use 4 digits, which means the fraction is out of 10,000). So in your case 925 means that 925/1000, or 92.5%, of the bracelet is silver or gold, depending on the metal used.

However, that only tells you what its value is as scrap metal. To determine the scrap price you can multiply:

(the fineness percent) X (the current price of 1 oz. of silver/gold) X (the weight of the bracelet)

then lop off about 1/3 to get a wholesale price.

However - it's also possible that the bracelet could be worth more than its scrap metal value due to a special design, being in Excellent condition, etc. To know that you'd need to have it appraised by a jeweller.
