Rock Gem Necklace Bead Jewelry String Stone Blue

Rock necklace that is adjustable. Not sure what the Stones are but they have weight. You can wear short or long. The metal beads don’t stick to magnet. This is the Blue Stone necklace. Items haven’t been cleaned. I do my best to show you color/style. I try magnet test to determine if it’s gold/silver/copper/brass metal bc so much jewelry isn’t stamped/vintage. I guess on material so no guarantee. I’m not liable so review all pictures & ask all questions-no returns/cancellations. Thanks!
