Old Amber Rose Necklace

Mysterious Old Amber Rose Necklace I’m not sure where or when this came from, but I found it amongst my great-grandmother’s old things. It appears to be etched glass. It catches the light at the right angle, and casts a little bit of a glow that reminds me of candlelight. Very romantic and warm. Also may or may not be haunted, not sure. Feel free to ask questions, comment, or offer :)
