Below Pt850 standard, can not be called platinum.
Its advantage is that anyone’s skin is not allergic to platinum, in addition to platinum also has strong, high melting point characteristics.
white gold is white gold, usually said in the watch white gold, refers to white gold, white gold (white gold).
Its main component is gold, because it is not natural white, so it needs to add other metals to change. It is worth emphasizing that white K gold is not platinum.
