Tomokoni Mine, Machacamarca District, Cornelio Saavedra Province, Potosí Department, Bolivia
This rich green and blue specimen of vivianite has and unusual crystallization. While long and prismatic on first glance, on close viewing the piece appears to be graduated tabular crystals that have grouped together. They have multiple chiseled and textured terminations. They are closely packed and arise from a deep brown sandstone matrix. Which can be seen in small amounts adhered to the bottom areas of the crystals. When backlit, this small cabinet specimen glows with rich colors of both green and navy blue and shows excellent transparency. This mine has produced what are some of the finest quality vivianite specimens ever seen. The crystal has contact markings on one side but doesn’t seem to be damaged although the natural terminations are somewhat jagged.
