18K gold filled, 4 mm beads
Mother of Pearl and Onyx Ying Yang charm
 
Gold filled is an actual layer of gold-pressure bonded to another metal. Gold filled is not to be confused with gold plating as filled literally has 100% more gold than gold plating. Gold filled is much more valuable and tarnish resistant. It is water friendly and will last much longer than gold plated jewelry. 
 
Onyx absorbs and transforms negative energy and helps prevent the drain of personal energy. Black Onyx aids the development of emotional and physical strength and stamina, especially when support is needed during times of stress, confusion and grief.
