Isn't this alluring? Not counting any part of the 3/8th's-inch inside diameter bale, this colorful Naja is 1.5-inches long. Likewise, it is 1.5-inches across the middle. Weight of the Naja itself is 16-grams, or .56-ounces. It's said that the Navajo emulated a saddlery design worn on the breast of the Spanish Conquistadors' horses. By no means is it a 'horseshoe.' Navajo makers have expressed to me that the semi-circular shape of the Naja form a perimeter shield keeping negative, or evil, away—whilst the opening at the bottom allows goodness to enter into one's center core. This attractive Naja by Robert Shakey ships with a solid-Sterling, 18-inch box chain. Complimentary USPS tracked Priority shipping within the U.S.
