Here is an above average quality, decorative piece of Banded Onyx from Arizona.  It measures approximately 7 1/2″ x  5 1/2″ x  9 3/8″ and weighs nearly 14 1/2 lbs.  It has awesome banding with an interesting mix of  dark Yellows, Brown and  Cream with neat highlights and cavities all in a good design. The color is even more vibrant when wet as seen in the last photo. A very unique addition to any rock garden.
