The termination is pyramidal with six faces. This is a big crystal weighing approximately 170 grams (my gram scale only goes to 100 grams so I had to weigh it on my postal scale).

Small Cabinet - 7.5 x 5.5 x 5 cm
Multi-colored 5cm Tourmaline crystal set in Albite with Quartz crystals. The Tourmaline is double-terminated with a red cap on the bottom. The rest of the crystal grades from a green core to pink, then a blue cap. The luster is matte due to a last generation of Tourmaline that grew on the surface. INterestingly, the last generation of blue Tourmaline appears to have coated the surface of the Albite which is white underneath but covered in a layer of blue.
