The original intent was for the Naja to hover just below the center of one's chest (over the solar plexus ), and traditionally at the bottom of a squash blossom necklace. Its shape forms a perimeter guard against the entry of evil influence. The 'gap" in the bottom of the Naja (please don't call it a horseshoe), thus allows goodness to enter into one's center core. This is a nicely made Naja ring by Navajo silversmith Robert Shakey. It's sturdy and quite attractive. It is size 7; hallmarked "ROBERT SHAKEY," and it weighs 15-grams, or .53-ounces.
