Platinum is soft. If it is put together with other jewelry, it is easy to scratch each other and leave scratches on the diamond ring, so platinum jewelry should be put in the jewelry box alone when not worn. In addition, collision may cause losses, so the collection of platinum must not be taken lightly. Jewelry boxes should be padded or suede, and each piece of jewelry should be stored separately to reduce the chance of collision. This is the answer given by Bao Ruitong.
