Calcite after calcite pseudomorph coated by lemonite on quartz

An excellent cabinet size specimen of steep calcite scalenohedrons, developed on quartz. Calcite crystals are covered by several generation of calcite aggregates and secondary coated by lemonite. In the end of crystallization process on the top of scalenohedrons were developed clear rhombohedrons with flat habit.
