Seconds quality Black Obsidian Pyramid with minor flaw. Towards one of the lower points on the pyramid there is a small natural opening within the Obsidian. See second photo.
Size: Each edge measures approximately 80mm.
Highly polished on all main faces, with amazing reflection and shine! Underside is unpolished. Perfect for large grid-work or as a scrying tool. Please be aware that the pyramid comes to a sharp point. Handle with care.
