Dendritic Limestone Cabochon

This material comes from Canada.  The black dendrites are a mineral inclusion not a fossil.  This cab is flat, no dome.

The cabochon measures 43 x 20 x 3.0 mm.  It has a girdle height approx. 3.0 mm and is sloped at 5 degrees for ease in setting.  The back is also polished.
