Cadmian smithsonite with large crystals and bright color. The cadmian deposits are layered into the outer layers of the large rhombohedral crystals (to about 1 inch in size!), leaving white and yellow zones when looked at in cross-section. However, this piece presents a solid mound of intensely-colored yellow. Ex Nauke Oechslin Collection, purchased in Africa in the early 2000s. 17 x 15 x 12 cm
