Gua sha tool artisan crafted from sustainably sourced Bian stone, an amalgamate of 40+ minerals known for their healing and rejuvenating properties. Some scratches visible on surface. White “veins” of various sizes may appear on the stone. These veins were formed as a result of a meteor striking a mountain in China 65 million years ago and are a sign of the Bian stone’s authenticity. This stone emits energy known for antioxidant and anti-aging benefits, including a measurable ultrasound pulsation and a far-infrared wave. It also emits negative ions, known to promote relaxation and overall well being.
