Diamond ring custard becomes black. It is generally caused by oxidation. You can go to Lao Fengxiang for free cleaning. If it is not caused by oxidation, it is a quality problem. If the diamond ring is still in the three packs, you can go to the store to negotiate.

This lesson should be replaced by a precepts. Because the original basic material is not very good.
Find a merchant to negotiate and return.
