Dendritic Agate stones are comprised of Iron Oxide (Orange) and Manganese Oxide (Black) inclusions inside the stones that make some very beautiful patterns. The word Dendritic comes from the Greek word "dendros" meaning tree, as the inclusions in Dendritic Quartz typically resemble plant life. What you typically look for in these gems are beautiful patterns and clear, clean Quartz. This stone displays some nice examples of both qualities. This stone also has a beautiful and unique purple color. The Agate is gemmy and the pattern quite intriguing. This stone is 100% natural and untreated. Cut at Kosnar Gems, Colorado, USA.  Enjoy!
