Vivianite Crystal Blade

Dark blue-green Vivianite with closely arranged blades, reflective lengthwise ridges and a strong elongated profile.

From the São Gabriel da Cachoeira area of Amazonas, Brazil, this Vivianite displays closely arranged blades with pronounced lengthwise texture. Reflective crystal surfaces catch the light along the ridges, drawing attention to the layered structure and individual edges.

The colour appears deep blue-green, becoming almost black in subdued lighting. Brighter reflections reveal green-blue tones and fine detail along the blade surfaces. Its appeal lies in the combination of deep colour, directional growth and sculptural shape.

The broad upper section narrows towards the base, while contrasting brown mineral material is visible on the reverse. The associated material has not been separately identified. Different views reveal the relief of the overlapping blades and the irregular upper edges.

Vivianite is a hydrated iron phosphate mineral. Its characteristic blue and green colours develop through oxidation, and the depth of colour varies between specimens. Elongated crystal growth and the relationship between reflective faces and darker recesses give this piece its individual character.
