Anonymous asked: like silver it also has the #525 or something like that.
corn answered: There are no standard rules available. If you have a yellow-metal bracelet, you might be lucky to have a full hallmark which states where it was made and the purity of the metal. Some bracelets may only have 14k stamped inconspicuously on the clasp.
14k gold represents 58⅓% (ie: 14k/24k = 58.333…%) purity [people who buy and sell gold know this]
Ultimately, only the acid test will prove how good your gold is.
