Description
Locality: Minas Gerais, Brazil
Vivianite is named after John Henry Vivian (1785–1855), a Welsh-Cornish mineralogist from Truro in Cornwall who discovered the species. Classic early specimens came from Wheal Kind at St Agnes and other Cornish mines.
Fresh vivianite is colourless or very pale green. As its iron oxidizes, the crystals darken through blue, greenish blue and indigo, and finally to black, which is why many specimens are deep blue-green to nearly black. It is also very soft, only 1.5 to 2 on the Mohs scale, with a perfect cleavage, and thin crystals can even bend.
Vivianite forms as a secondary mineral in the oxidized zones of metal ore deposits and in complex granite pegmatites. It also grows in lake sediments, bog-iron ores and peat bogs, and can replace organic material in fossil bones. In Brazil, the Handbook of Mineralogy lists it from the Énio pegmatite mine near Galiléia, Minas Gerais.
This one of a kind Vivianite specimen from Brazil features dramatic dark blue-green to nearly black Vivianite blades partially encased in a rich, iron-stained brown matrix. The crystals show a striking fan-like formation with long, glassy, striated blades that reveal flashes of deep teal, green, and blue when viewed in the light. The earthy matrix adds strong contrast, giving the specimen a rugged natural presentation with excellent depth and visual character.
This piece stands out for its large bladed Vivianite crystal sprays, glossy luster, and natural iron-rich coating across the host rock. The exposed crystal sections display beautiful translucency along the edges, while the darker portions create a bold, sculptural look ideal for display or collection.
Vivianite is named after the British mineralogist John Henry Vivian, who discovered the species. It is commonly associated with emotional healing, heart-centered awareness, compassion, renewal, patience, and gentle transformation.
