•Cut from large Nodules showing striking design and colors
•Completely polished on front side. Specimen is around 3/8 inches thick
•Similar to a geode, except that these are sedimentary, and always have dark brown (Aragonite), and orange or
yellow Calcite, sometimes crystalized. *There are the fossilized remains of a prehistoric Cephalopod visible.
- *One of the photos shows the slice held up to a light source to show how the light comes through as a “Glow” .
The best way to display and enjoy these slices is to set them in a windowsill that gets either morning or evening light.
That way these act like stained glass and really come alive.
