Gold Floating Heart & Dangling Star Charm

Very dainty vintage piece; Gold chain with extender hanging a Goldtone floating heart pendant. Attached is a star-shaped Mother-of-Pearl charm. Pearly white star laying on/in the edge of heart. This was a gift and I do not know the authenticity of the Mother of pearl-looking charm. There is no purity numeric stamping on the chain, or the clasp - but it's a very nice gold chain that fits 14-17" neck size.
