Description

Here is another amazing spiky crystal group of calcite from the Sifnos Island, a very rare locality in collections. It is an stalactitic growth, with a hollow core at the base. The aggregate is formed by rhombohedral crystals of calcite that are mostly twinned, and generating nice groups of threefold symmetry. It shows a nice whitish blue fluorescence under UV illumination, especially intense under long waves.

It was collected in the early 1980’s by Herman Torfs (specimen 92), in one of the multiple trips to Greece. Mr Torfs numbered his collection not by piece but by locality, so all those coming from the same place have the same number.
