This cabochon of Sonoran Dendritic has beautiful patterns. This is simply called Sonoran Dendritic because of the strong dendritic patterns and is found in the state of Sonora, Mexico. Sometimes the background can contain some pink color and be softly banded like hickorite or wonderstone. The sealed fracture pattern is similar to the sealed fracture patterns in the Owyhee Jasper from Oregon and the maroon color of the dendrites is very similar to the color of the dendritic pattern in the jasper from New Mexico called Apache Sage.
