925 Silver Minimalist Women's Wedding Ring Simple and Fashionable Women's Party Jewelry

Beautiful but it looked different in the photo

3.5 weeks to Kyiv, very pink metal, size fits, somewhere around 19.5 our size, looks good on the thumb. But there is no hallmark, only the ring size is engraved Leaves a black mark on the finger when worn, this generally means it's not silver

The ring doesn't have a hallmark, what kind of ring did they slip me.
