If you view the extra photos (link below) you will see how the artist placed the unusual dark striations in this piece of onyx to color this gemstone bird's head. The tail has a double layer of white dolomite on top of the onyx, and the orange beak is calcite. The amethyst base is 7" wide, & holds scores of perfect terminations. This one is a true Brazilian Treasure!
