A very typical and also superb combination piece from the well known Richterbruch ( Richter Quarry ) of Hammerunterwiesenthal in Saxony. Here we have a super and PRISTINE cluster of strangely but anyway perfectly formed Calcite, superbly set in the center of Natrolite- covered matrix. The Natrolite here has light amber coloured tips what gives a bit of contrast to the rather creamy Calcite. I know, Calcites from this locale are not very rare, but this one with its strange form and integrity is. Definitely GREAT AESTHETICS.
