This specimen consists of a massive piece of dark gray ullmanite, showing small distorted crystal faces on one side. A part of this face is obscured by calcite. There is not enough crystalline material showing to be able to study the isometric form. This specimen reminds me of the habit shown by skutterudite in Morocco.
