In the 3rd quarter of the 19th Century, Navajo and Pueblo groups began producing silver jewelry not only for personal adornment, but for trade and sale. Silver, turquoise, coral, mother of pearl and jett were some of the more popular materials used for making bracelets, pins, rings and the highly recognizable squash blossom necklace. Because much of an individual's wealth was "tied up" in their silver jewelry, it was often pawned at trading posts when cash was needed. This gave rise to the familiar term, "old pawn" jewelry.
