Seven stone Kingman turquoise Navajo Naja ring, by Robert Shakey

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.  Always complimentary USPS tracked Priority shipping within the U.S.
