Vintage Ross-Simons mini charms w/chain necklace

4 vintage gold over silver mini Ross-Simons charms ( fleur de lis, 4 leaf clover, cross w/heart and star) on Ross-Simons gold over silver chain. All marked with the “R” hallmark. See pics. I could not find anything similar. The chain 17 3/4 in length. This one is just adorable! The gold overlay on chain and charms are in good condition. The pics show it up close and larger for detail, but it is very dainty.
