Super cool dark Septarian Eggs and pieces from Madagascar with deep brown calcite fronts. These eggs have a classic brown and nearly black coloring with a polished back and a crystal front. The face of these will have a subtle shimmer to them in the right lighting due to the small dogtooth calcite formations. Some have some white or clear calcite or barite on them too.  A couple of the larger eggs can self-sit, but the other eggs will come with a free plastic ring.  The small pieces can only lay flat.
