A classic tubogas necklace from the 1930s! This style has become such a standard that many don't know that it actually originated in the 1930s. Its flexible design is created by tightly interlocking two long strips of gold and was meant to do the most with the least at a time when gold was scarce. Though it is strong and looks solid, it is actually hollow on the inside giving it a bold, heavy look with a comfortable weight. This 14k yellow gold necklace measures about 15 inches long, unstretched, and about 3/8 inch wide.
