As universals symbols go, Om (or Aum) ranks right up there. Initially used by all the various dharmic religions, who considered it to be the original sound/vibration of creation, it has become popularised to represent 'peace', and to be a symbol of spirituality and inner contemplation. Whichever way you want to take it, this classical and stylish piece will up your frequency.
The Om ring in the photos has gold-plated accents. It is also available just in silver for about $15 less/piece. It is hand crafted from Sterling Silver and is stamped on the back with the Mercurious name and logo and 925 to guarantee authenticity.
