Nickel white gold alloys also have a greater hardness than palladium white alloys as a general rule. This dual combination offers natural colouration, with the benefits of both metal choices. Whilst it may be true that platinum is harder than gold in its purest form, 18kt white gold is mixed with other metals, most commonly palladium, silver and copper to make it harder. The karat of an alloy indicates in what proportion pure gold is mixed with the “filler” metals in it. As a result, jewelry made with 14K and 18K gold will be more malleable and easier to bend. Barium produces bright greens; strontium yields deep reds; copper produces blues; and sodium yields yellow. White golds are available up to 21 carat.

To avoid this, make sure to check what metals your white gold alloy is composed of before you buy. 18K white gold has the highest purity – 75% of it, or 3/4 ths, is pure gold. They also have low working-hardening rates, making high deformations between anneals easily achievable. Technically, metallurgists measure hardness of metal on the Vickers scale, which tests the plasticity … As you can see from their karat numbers, 10-karat, 14-karat, and 18-karat white gold differ from each other with respect to how much gold they contain: All these numbers are interesting, but how are they relevant to your decision regarding what karat jewelry to buy?
