Tiger Eye Bowl - Round & ThickTiger Eye Bowl - Round & Thick"Fierce Protective Stone” An exquisite polished bowl. Chatoyant and one of a kind. In Feng Shui, the ancient Chinese art of placement, balance comes from the combination of yellow (earth colors) and black/dark brown (water colors). Because yellow is also associated with communication and dark colors with independence--as well as strong self-discipline--tiger iron gives a strong, clear message when worn. That's a big part of tiger iron's spiritual power.
