Boulder opal pendant

I made this pendant out of a rough stone that I bought many years ago. However, it had such a special shape that I never knew what to make of it. This shape was reflected in the end product. The stone unfortunately has a small flaw that could not be completely removed during the cut (as can be seen in the pictures).
 Please note that this is a handmade, unique item made from natural materials, so it may contain bumps, inclusions or similar imperfections in nature.
 You will receive exactly the piece that can be seen in the pictures.
