Vivianite Crystals on matrix - Height: 10.5 cm - Width: 5 cm- 180 g

Vivianite is a fascinating mineral known for its deep blue to greenish-blue coloration and excellent crystal form, frequently found as hydrated iron phosphate. It commonly occurs as crystals on a matrix, often with translucent to transparent blades or prismatic shapes. Vivianite can change color and darken upon exposure to light due to oxidation. This specimen, measuring over 10 cm high and weighing around 180 grams, showcases well-formed vivianite crystals perched on their natural matrix, illustrating the mineral’s elegant aesthetics. Vivianite’s appearance and development reveal interesting geological conditions, including sedimentary and hydrothermal environments. While not typically a mainstream gemstone, vivianite specimens are treasured by mineral collectors for their unique color and crystal structure.
