Silver tone rhinestone heart key necklace

Sweet vintage heart with keyhole and matching key pendant on a 15” chain. Lots of sparkle on the front of heart with lots of clear bright rhinestones. The key is an old fashioned skeleton key style. Chain has a 3” extension chain for a total of 18” approximately. Vintage from the early 90s. No marking stamp or name on this cute little necklace. Looks a bit like a locket but does not open.
