Yes, white gold can be stamped with "625" to indicate its purity. The number "625" is typically used to denote that the white gold contains 62.5% pure gold. This purity level is commonly seen in white gold alloys used in jewellery making. White gold is created by combining gold with other metals, such as palladium, silver, nickel, or platinum, to achieve its characteristic white hue. The resulting alloy is then stamped with a marking to indicate its purity level. For instance, "625" signifies that the metal is 62.5% pure gold, with the remaining percentage made up of other metals used in the alloy mixture. It's important to note that the stamp "625" or any other purity mark might vary depending on the country's regulations or standards. Therefore, when purchasing white gold jewellery, checking for these purity markings can help ensure you're getting the quality and purity level you desire.
