Chicote Grande Mine, La Paz, Bolivia
At least 4 different Vivianite crystals intersect to form this thumbnail specimen. All are in excellent condition, showing no damage, and achieve dimensions of 0.9 x 0.4 x 0.1" (2.3 x 1.0 x 0.3 cm). Their monoclinic bladed form is very good, with well-defined edges and clean faces that possess a pearly luster. Both deep blue and green colors are visible in each crystal, and all are transparent and impressively clear. They rest on a thin crust of pyrite that acts as a base.
