Here we see a superb single crystal of scalenohedral Calcite with relatively enormous dimensions,- up to 6,2 cm in lenght. It is superbly formed, sharp edged and well terminated. It is gemmy and almost colourless with partially rust-red coated faces close to the tip. The luster is great as well and so far I can see, there are no significant imperfections worth to report. Very good old time material.
