It's different. Platinum is a naturally occurring white precious metal with a very high purity. The white gold on the market should actually be called white K gold, which is an alloy made of gold and other metals, and does not belong to the true sense of white gold, which is a synthetic metal.
Platinum is a naturally occurring white precious metal with very high purity, so its texture is relatively soft, and it is easy to make a variety of styles, but not suitable for inlaying. Because it is a naturally occurring color, platinum will always maintain a white luster and will not fade.
The white gold on the market, which does not belong to the white gold metal, should be called "white K gold" or "18K gold", is a kind of alloy made of gold and other metals, is a synthetic metal, and therefore its texture is harder than natural platinum, suitable for inlaid jewelry. But because it is synthetic metal rather than natural, it will fade and slowly turn yellow as it is worn for a long time.
From the investment level, the investment value of platinum is higher than that of white gold on the market.
