Description

Technical field [0001] The present invention relates to a white precious metal alloy composition. More specifically, in a specific embodiment, the present invention relates to a white precious metal alloy composition suitable for manufacturing jewelry and other finished articles. In addition, the present invention also relates to a method for manufacturing finished products from the white precious metal alloy composition. Background technique [0002] In recent years, the popularity of white gold has been steadily increasing, resulting in a corresponding increase in the demand for platinum jewelry, especially in Japan and China. Platinum is particularly popular because it is relatively cheap compared to platinum, because the public cannot easily distinguish platinum jewelry from platinum jewelry. In other words, for the wearer, platinum jewelry can maintain the aura and uniqueness of platinum jewelry at a greatly reduced price. [0003] Many jewelry manufacturers can make jewelry...
