Long Exceptional Vivianite Crystal - Deep Green Lustrous Specimen - pleochroism - legendary find in BRAZIL - Height: 6.3 cm - Width: 1.5 cm- 4 g

Vivianite is a captivating phosphate mineral known for its striking deep green to blue-green hues and exceptional luster. This particular specimen hails from Brazil, a renowned source for high-quality vivianite crystals. Notably, vivianite exhibits pleochroism, meaning it can display different colors or intensities when viewed from different angles, adding to its visual intrigue. Crystallizing typically in prismatic forms, vivianite contains hydrated iron phosphate, giving it its characteristic coloration. These crystals often form in sedimentary environments or oxidizing conditions where iron is present, sometimes found within fossilized organic matter or clay beds. Collectors prize vivianite specimens for their vivid colors and translucency, though the mineral can be sensitive to light and moisture, sometimes altering its appearance over time. This long, lustrous crystal, measuring over 6 cm in height, exemplifies the mineral's rich color and appealing crystal habit, making it an exceptional piece for mineral enthusiasts and collectors alike.
