This 89.77 gram raw, green-blue high-quality Vivianite specimen from Brazil has extreme translucence and vivid coloring with pleochroism. The specimen is made up of 2 pieces of botryoidal Chalcedony with sprays of vibrant Vivianite blades growing between them - almost like a vivianite "sandwich"! 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 70 x 50 x 40 millimeters.
