Sea Shell Brooch, Unknow maker, Late 20 century

Hello Everyone.
Good evening from Ontario.
I found this Wonderful Sea Shell brooch at the Mission Thrift store last week, I research it with no luck, not easy when no maker mark.
Gold plated with Rhinestone applied in swirl manner around the Shell with an enormous faux pearl at the tip, extremely well done in perfect condition.

This brooch is 2.25 inches long by .75 inches wide.

Mant thanks for looking.costume
