Crystals and gemstones are solid minerals from the earth's soil and atmosphere that bring about feelings of physical, emotional, and spiritual wellbeing. Essential oils enhances these properties by providing instant aromatherapy. Choose a crystal or gemstone along with an essential oil, to personalize your roller ball for your special needs. Use the roller ball as often as need on places like wrist, under nose, and temples for aroma and crystal therapy. Not sure which essential oil to choose?
