I have a few pieces of vinatge costume jewlry and am looking for a website that I can ask an estimate of value?

I have 2 silver and rhinestone G cleff pins (1 large, 1 small).
A pair of daffodil multicolored stone screwback earrings.
A green leaf with pearl seeds pin.

You’re better off going to a local reputable jeweller with the pieces.
