Cocobolo Ring Shake
Ring shake is a term which describes when pressures inside a piece of wood cause it to cleave along the growth rings. In many cases it happens becauase the piece came from the bottom of the trunk where it flares out towards the ground.
This piece of cocobolo, in addition to having stunning color and grain patterns had two instances of ring shake. It was unusable in a furniture context but I secured the pieces together and mounted it on our wall to enjoy the beauty of it on a daily basis.
