This was given to me by my mother who knows more about antiques than I do.  After reviewing in an antique book, she had written down on a slip of paper-

Antique German Silver Mesh Purse Two cabochon amethyst stones Art Nouveau 1900 Made by E&C #43 

I could not find a comparable silver mesh purse on ebay with amethyst stones, nor did I see E&C on purse, so I really don't know it's true worth.  I do know German silver is less than .925 silver, but I am not sure what quality this purse is.

Thanks!
