Indigenous Nutria travertine is a found stone on the Nutria area of the Zuni Pueblo reservation. It can be either travertine, agate or jasper. The rich tertiary colors are like a warm cup of coffee. Melvin Eriacho is a master carver who recently brought by a beautifully polished Nutria travertine Frog. The attention to detail is extraordinary like the two raised skin ridges called dorsolateral folds that run from the eyes down the back or the wonderfully realistic webbed feet. Charming eyes are from turquoise inlays. About 4 1/2" long, 3 1/4" wide and 2 1/4" tall.
