This 75.78 gram raw, green-blue high-quality Vivianite specimen from Brazil has extreme translucence and vivid coloring with pleochroism. The specimen is made up of a partial cavern lined with botryoidal Chalcedony with sprays of vibrant Vivianite blades growing from it. 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 65 x 40 x 35 millimeters.
