是你自己完全搞错了。铂字读Bo(2)不读白。铂金是platinum, 白金是white gold,二者首饰的差价很大

我自己的首饰里铂金，白金，黄金（24K,14K,18K的）都有，搞得清楚他们的材质价格的区别。

铂金Pt950网上有详细说明：不同金属纯度都有不同的数字说明的

Pt950 is a stamp that indicates a piece of jewelry is 95% pure platinum. The remaining 5% is made up of other metals. 

 

Explanation

• The "Pt" in the stamp refers to platinum on the Periodic Table of Elements. 
   
• The "950" refers to the number of parts platinum per 1,000 parts of the metal. 
   
• The stamp can be laser-etched or stamped onto the jewelry. 
   
• Platinum is a precious metal that is dense, durable, and resistant to tarnishing and scratching. 
   
• Platinum is often alloyed with iridium or ruthenium to increase its hardness. 
   
• Platinum is a popular choice for diamond settings because of its white color and durability. 
   
• Platinum jewelry can be more expensive than white gold jewelry because of its purity, density, and longer fabrication time. 
   

Platinum jewelry is often hallmarked with the metal purity. For example, 18K gold is stamped with "750" and sterling silver is stamped with "925".
