Om is the symbol of the Third Eye chakra, is the seed sound of that chakra, and is also traditionally the symbol for All That Is.  When Om (aum) is chanted as a mantra, it is done so to connect with Divine energy.  This Om pendant is my design, hand cut from sterling silver sheet, and brushed to a matte finish, for a soft subtle reminder of connection to the Divine.  On an 18" sterling chain, finished with a sterling silver lobster claw clasp.
