A "naja" is what some people refer to as the horseshoe at the terminus of a squash blossom necklace. Naja means "crescent" in the Dine' (Navajo) language. Some say it mimics a design on the center piece of the bridles on horses the Spanish rode into the Native American territories in the Southwest area of North America in the 1500's. Another, more esoteric, explanation is the crescent-shaped semi-circle—which normally hangs immediately over one's center core—serves to form a barrier against evil entering the person wearing it. The small gap opening at the bottom then allows goodness to enter up and into one's inner being. This naja has one nice Royston turquoise stone, and a lot of nice silversmithing, including an intricate, large bale. Length, not counting the bale, is 2.5-inches, and width is almost two inches.
