The stone was found in the Spokane River. It was cut into a smooth, round cabochon. We let the natural character of the dark stone dictate its final shape. It has a deep, polished surface with subtle flecks. We've waded the Spokane River for over 30 years. It runs right through our backyard. Rufus, our beloved dog, loved it there. Every piece in the Spokane River Stones and Stories Collection comes from the river we know best. Each stone has a story of survival. — Bob & Janyce, Rockhound Studio, Spokane Valley WA This round cabochon features a high polish finish. The pendant measures approximately 25 x 25 x 7 mm. This piece is set in a bronze tone alloy bezel with an integrated bail, ready to wear on its included cord. Spokane River Stones and Stories Story Spokane River Stones and Stories Collection
