Description
A strange and beautiful pseudomorph, specifically a cast, of light green quartz that formed on crystals of calcite, with the calcite later being naturally etched away, leaving the quartz with the form of the calcite crystals; EXCEPT for the beautiful tiered structure of the faces, which was not part of the original structure of the underlying calcite, but an added "decoration" that makes them look like some sort of ancient pyramids or ziggurats. 10.7 x 8 x 5 cm
