VintagePoland Sterling Silver Oval Amber? Possibly?Cabochon With Flowers Pendant

I’m not entirely sure what the cabochon is as I have not tested it. I do know that it is sterling silver also it is signed and stamped on back of pendant it is polish signed Poland has patina but looks amazing see above for measurements Scratches to the surface and to the metal bit it is very old so that can be expected with older items of any kind also has a floral motif design carved on back so it looks like it’s inside of the cabochon fabulous piece
