Featured in this lot is this Navajo obsidian sphere necklace circa 1940's. The necklace features a wonderfully and professionally crafted obsidian construction that shows a shaft and loop clasp that is beautifully decorated. The condition of this necklace is fair to good with one crack in the sphere bead close to the clasp but otherwise shows good overall condition. The measurements of this necklace from clasp to clasp are 19" and shows a diameter of 5/8".
