Matte Black & White Onyx Beaded Bracelet, Boyfriend Girlfriend Jewellery Single Piece, Men's jewellery, Yin Yang Bracelet

Onyx is a protective stone worn when facing adversaries in battles of conflicts of all kinds. Onyx is formed by the deposition of silica in gas cavities in lava, which results in the distinctive bands or stripes we see in the stone. The best way to clean an onyx is to wipe it clean with a moist cloth. It is not recommended to use any sort of ultrasonic cleaners or ammonia as the stones may be porous and therefore might absorb chemicals, even soap, which can build up inside the stone, causing discoloration.
