This is one fabulous necklace. The Kingman Turquoise disk beads are older. They are perfectly graduated. Each bead is separated by a copper spacer bead so the Turquoise falls perfectly and does not twist when worn. This is truly a statement necklace. The Turquoise disks measure from 1" across to 1/8" across and is 22" long. It is very rare to see a necklace with such perfectly matched graduated Turquoise disk beads. This Necklace is made by "Elvira" who is Navajo. Note this necklace does have some weight to it.
