Usually, most jewelry brands cannot exchange platinum for gold. Platinum can only be exchanged for platinum jewelry or other jewelry. Because platinum has no preservation function and gold has preservation function, platinum cannot be exchanged for gold, but gold can be exchanged for platinum. The value-preserving function of gold can be directly used as money when the old one is exchanged for the new one, so it can be exchanged for other things.
The physical properties of metallic materials such as platinum are unstable. If it is made into jewelry, it is easy to deform or break, so be more careful when maintaining platinum necklaces.
