Vintage Baltic Amber Heart with Frog Pendant (no chain).

This is from my own personal collection, I’m a huge frog collector. I’ve had this since the early 90s. It has been displayed with all my other frogs in a curio cabinet. I have never worn this as a pendant that is why there is no chain included. Please check out the photos carefully, you’ll notice where the chain would go through. It appears to be tarnished however, I do not know what the metal is on this pendant. There are no markings. If you have any questions, please feel free to message me.
