This bola has a Thunderbird facing to its left. It has a variety of stones inlay including MOP, coral and turquoise.

The Thunderbird slider measures 1 3/4" by 1 1/4" and the tips are 2 1/4."

There are no marking on the slider, however, my supplier assured me it is sterling. Also, he stated that the bola is from Thailand and not Zuni crafted.
