VIVIANITE, PYRITE

On a matrix formed by small but bright siderite crystals they are disposed very aerial some sharp crystals of vivianite, prismatic shape, lanceolated, thin, brilliant and with an excellent transparence. The green color is excellent. A very displayable specimen. Due to the vast cassiterite deposits in this mine, removing phosphates is strictly forbidden, and the levels upon which these beautiful specimens are found have been intentionally flooded. The main crystal is: 4,6 x 1,8 x 1 cm.
