Spiderweb Bisbee Turquoise Necklace-107

Very nice hope he style spiderweb Bisbee Turquoise necklace. We got this necklace in a fairly large Bisbee Turquoise Collection in Flagstaff, Arizona a couple years ago. It has nine beautiful Bisbee Turquoise gemstones and several are spiderweb. This is a one of a kind piece that was made in the 70s. It has a makers mark but I cannot make out what it is.
