A substantial piece of sterling silver cradles the large pieces of coral and Blue Diamond Turquoise. Measuring 3 3/4" long at the widest point, the bolo is decorated with silver dots and silver ends to the 36" braided leather cord. The Blue Diamond Turquoise mine was located in central Nevada, opened in the late 1950’s and was mined up to 1980. The stones that this mine produced, usually large pieces in plate form, look a great deal like Stormy Mountain turquoise because of its black smoky matrix. This stone features dark smoky matrix surrounded by a brilliant blue. The characteristic black chert is ever-present. This mine is now closed and buried under thousands of tons of rock.
