This is a fine sterling silver necklace set with three bars of King's Manassa Turquoise from a Navajo silversmith. The piece is stamped on all three pieces "Sterling" and shows a total of fifteen polished cabochons of nice deep green turquoise from the King's Manassa Turquoise Mine. Found in Manassa, Colorado and sometimes referred to as "King Turquoise Mine", the mine was actively mined by Native Americans for centuries but was later discovered by I.P. King in 1890, with the King family operating it until its closing and originally being called the Lick Skillet Mine. The mine is not active and turquoise from there is uncommon and rare. The piece shows a sterling silver circle ring with a dangling pendant and two articulated necklace pieces all along with sterling silver handmade chain link necklace strand and a .925 lobster claw clasp. The necklace measures 18.5"L with the pendant section being approx. 5"L. Total weight of 39.4 grams.
