All of our earrings (studs not included) are made with some, if not all copper wire. Copper has been used for thousands of years for its many healing properties. It is a good conductor of heat and electricity as many know, but it is also a great conductor of energy and vibrational frequencies (amongst individuals, auras, crystals, etc.). Copper is said to help physically with joint wear and tear, arthritis, circulation, detoxification, energy, inflammation, metabolism, and more. It is also attributed to benefits in communication, cleansing, purification, self-esteem, channeling, releasing, etc.
