Benjamin Adam’s London crystal heels

These are a beautiful pair of heels. I was gifted them from my dad for my wedding the didn’t happen. One is oxidized from being display shoe I don’t know if it can be cleaned or the other one dyed to match. They are two different sizes. One is a 7 the other is a 7.5, I was unaware of the size difference until after I got them home. They were purchased in California and I live in Oregon so I was not able to return them. I got the 7 stretched to a 7.5
