I bought a diamond ring (with a certificate) in Jin oppo. The inner ring of the diamond ring is only engraved with pt950e d033.1ct, without the words "Jin oppo". Is there a problem with this diamond ring?? What does "e" mean??

Pt950 indicates that the metal fineness is platinum.
d033.1ct indicates the weight of the diamond.
this is the mark that must be marked when the jewelry leaves the factory.
that E may be used by merchants to identify. It doesn't matter much.
Gold Opal is not marked because the inner arm of the ring is small, Some businesses will not choose to type it. It will be too complicated. In fact, if there is a location, customers can type their own name or favorite words. Both Chinese and English can be used. For example, love. A hundred years of love.
