Antique Silver Claw red orb watch fob circa 1890s.

Antique Silver tone ? claw red orb watch fob circa 1890s. This is not sterling silver. There is a two tone. Not sure what the metal is. This is not marked as far as I can tell. Wearing on sterling antique chain. This listing is for the fob only. I have owned for decades. Believe I bought in UK. Mint condition. I’m not sure what the ball is, likely glass or lucite. It is reddish in the light. Lovely statement piece. I am not a jewelry expert. I am listing this item as described when I purchased it. Please keep this in mind.
