Vintage Sterling Religious Charm Necklace St Christopher & Virgin Mary Miraculous Medal

I have left this necklace together in the way I found it. The chain is marked sterling and measures approximately 18 inches long. On the chain are two medals- on is a St Christopher marked Sterling and measuring 7/8ths inches tall with the bail. The miraculous medal is so precious- it is marked ster on the back and is a two tone heart and medal. This miraculous medal measures approximately 11/16ths of an inch tall including the bail.
