This is a 100% natural Rose Quartz Heart Shape Stone. Rose quartz is called "Love Stone". People believe that the powerful energy from Rose Quartz can bring love and enhance love in virtually any situation. The listed images shaw a pair of Rose Quartz Hearts, but in this auction you only get 1 heart. The rose quartz heart is 3.5cm x 3.5cm x 0.7cm. The rose quartz heart weights 38g. I purchased these 2 pieces around eight to 10yrs ago. They are never used.
