Polished Septarian Stone Egg. 300 grams.

This polished Septarian stone has a unique earthy brown and tan colouration with dark brown crackle-like patterns. 300 grams. It's smooth to the touch and egg-shaped. Can be compared to a turtle egg. Decorative piece, on desk mantel, or aquirium. I have one in my aquirium and the fish like it.
