Avon "Birthday Heart Pin" for April goldtone New on foam card, but not the correct box.
From 1992.
Or, just a very pretty golden heart with ribbon and rhinestone - it doesn't have to be a "birthstone".
It is about 1 ½" by 1 ½".
Sandra Sturdivant, in her book "Identifying AVON JEWELRY", described this as "gold heart with birthstone accent."
