Vintage Costume Jewelry:
- Broken Amber Brooch; pin is magnetic metal, had hallmark MET for which I have found was used in Poland as a mark for metal; so the amber could be the Baltic one.
- Ring - is defective, missing ring part; metal plate bellow the stone shows silver or silver plated signs; burn out signs are from someone had tried to weld it by regular metal welding machine unsuccessfully; non-magnetic
I can not 100% confirm it is amber, but best of my knowledge and skills (and test I've run) I believe it is.
I am selling it as a lot and as defective costume jewelry.
