These are zodiac rear view mirror hangers. They're handmade with epoxy resin, colored with paints, & poured into gold & silver plated open back zodiac bezels. Both colors are then put on a rose gold chain to compliment all the colors in this galaxy theme. Some feature the constellations there named for, & they all have Iridescent star glitters inside. They measure about 7'' - 8'' long, depending on which one you get.
