Chain total length is 16” , handmade, I’m pretty sure the metal chain is anodized silver and has some spots of patina (please see photos) I’m really not sure what the stones are, each seems a bit too heavy to be resin and too many pore variations that are too random so appears and feels like some sort of natural stone.., each bead is not the exact same size and is about 1” long shaped like a strawberry/teardrop, hanging from each bead is a smaller black faceted bead, most like onyx. I’m just going to call them lava beads though I’ve never seen red black ones before, so possibly coral due to the pores being abnormal. Total of 10 beads on the necklace. About 85g weight total. Nice vtg preowned condition, can use a mild cleaning with water and vinegar/backing soda. Shipping on multiple smaller items such as this can be combined, local pickup available
