TOP RATED The Aura Stone is our patented body gua sha tool designed to tighten, tone, sculpt, smooth the skin. It also stimulates energy flow, releases tension, and smooths connective tissue in dimpled areas. Unlike other gua sha stones typically made from quartz, the Aura Stone is composed of Bian stone, an amalgamate of 40+ minerals known for their healing properties. Each edge of the tool is intentionally architected to enhance the traditional Chinese practice of gua sha. Known for its rejuvenating properties, Bian stone was created when a meteor struck a mountain in ancient China. It is said to emit ultrasound pulsations, far infrared rays, and negative ions as a result of the cosmic impact — all of which are known for their antioxidant and anti-aging effects on cells and DNA.
