A very large specimen featuring numerous transparent colorless modified Calcite rhombohedrons on a matrix encrusted with pale brass-yellow microcrystalline Marcasite. The Calcite rhombohedrons are lustrous and gemmy and are up to 3 cms in size – a beautiful show piece with its size and luster – it’s as if it is covered with diamonds! The Calcite rhombs populate every side, even the bottom. This piece is extremely aesthetic with excellent contrast, crystal formation and luster and is in excellent condition.
