2 Necklace Lot Turquoise Dyed Howlite Nugget Pebble Chip Bead Multistrand Layer

2 turquoise dyed irregular shaped howlite chip, pebble and nugget polished stone bead necklaces lot. These may also be magnesite, TBH I don't know how to tell the difference. 1) Twisted two strand with lighter color beads. Clear glass beads at the ends. Silvertone barrel clasp. 18 1/2"L. 2) Three equal strands with slightly bluer and darker color beads. Silvertone finish round acrylic spacer beads (the finish is worn in some places). Silvertone lobster claw clasp and end chain. 20 1/4"L. Aside from the spacer bead issue on the three strand, these are in good condition.
