Sonora Dendritic Slabs feature maroon dendrites on a blue and tan landscape, maroon plumes with a pink background, or an almost hickoryite orange and yellow swirl. Slabs range in size from 1.75" - 8" wide and 4 mm - 6 mm in thickness.

Pictures show the material wet and dry, with examples of individual slabs.

Rough slabs are used primarily for making cabochons, and are cut/prepared for this purpose. Because of this, it is possible to receive slabs that are partially broken or have old price markings, as they are intended to be processed further.
