This 266.20 gram raw, green-blue Vivianite specimen from Brazil has extreme translucence and vivid coloring with pleochroism. The specimen is made up primarily of matrix stone with a distinct edge of crystallized Vivianite. It sits nicely as a cabinet piece and includes layers of botryoidal chalcedony. This fragile specimen is just 1.5-2 on the hardness scale, so it is quite fragile and to be handled with care. It will retain its coloring best out of direct sunlight, as the iron content can tarnish and darken the color in the sun. This specimen represents a high-grade example of this sought-after collector’s mineral. It measures approximately 110 x 50 x 50 millimeters.
