Distinguishing original gold from imitation 1

One of the ways to distinguish gold from gold is to check the numbers and codes engraved on it. These codes are engraved on gold in order to provide complete information about the product to buyers and sellers. If you check the gold and notice that one of the codes 375, 500, 999, 958, 916, 750, 585 and 583 is engraved on it, you can be sure that the product you are holding is a gold artifact. One of these codes is engraved on all ornamental gold. Only in some old gold, these codes cannot be seen. In this case, the gold rate detection device is used to detect the gold rate. If the engraved codes are something other than the codes mentioned above, the gold seller has delivered a fake product to you.
