Sterling crown pin...need help with ID please

[eggs3]

I have this pin that I bought many years ago.  I think it says sterling on the inside verticle section.  Measures about 1 1/2 inches tall.  Wondering if anyone has suggestions on the maker, date, and/or if the big stones are glass or something else.  Many thanks for any help
