Antique pearl earring

I’ve just come across a bag with a handful of scrap metal bits and bobs , noticed this that I didn’t see before, quite shocked as I can see it’s antique looking and silver at first glance , but considering it’s been amongst metal and al sorts of rubbish the pearl looks amazing, got me wondering the history of this earring, wondering if it’s real , I’m sure those kind of findings are Victorian , hopefully someone knows.
