This is the turquoise, spiney-oyster shell, and bronze mix 'stone' that is popular now. We like it better when turquoise is predominant, like here. The three ingredients are compressed into a brick and sold to the artists that way (see pic below). This pendant comes with the pictured 18-inch, solid Sterling silver box chain. Length of the pendant, not counting the bale, is 1 and 5/8th's-inches, and a little over 5/8th's-inches at the widest point. Hallmarked "ROBERT SHAKEY." Always complimentary Priority shipping within the U.S.
