4, gas spontaneous combustion method
The first step is to rub mercury on the ring, the real platinum will not be contaminated, and gold, silver, etc., will be contaminated with mercury.
Then file some powder into a hydrogen peroxide bottle at the edge or middle depression of the white gold ring, and the real platinum can act as a catalyst to promote the hydrogen peroxide decomposition, release oxygen and flip up and down. But doing so will also cause some damage to the jewelry.
