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.
Ludlamite, the green iron phosphate growing with the vivianite here, honours Henry Ludlam (1824–1880), a London mineral collector. It forms in complex granite pegmatites as an alteration product of earlier phosphate minerals.
This one-of-a-kind Vivianite with Ludlamite specimen from Brazil features pale to medium green Vivianite crystals alongside green Ludlamite, nestled inside a naturally rounded, iron-rich brown matrix. The specimen has a striking geode-like presentation, with green crystal clusters spread across a dark, earthy interior and framed by a textured, rust-colored outer rind. The crystal growth shows soft luster, translucent green tones, and natural white-to-cream mineral accents, giving the piece an organic and highly collectible appearance.
This specimen stands out for its unusual bowl-like matrix formation, contrasting green Vivianite and Ludlamite crystal pockets, and richly textured exterior. The combination of earthy brown host rock, dark interior matrix, and fresh green phosphate minerals creates a beautiful natural display piece with strong visual depth from every angle.
Vivianite is named after British mineralogist John Henry Vivian, who discovered the species. Vivianite is commonly associated with emotional healing, heart-centered awareness, compassion, renewal, patience, and gentle transformation. Ludlamite, another green iron phosphate mineral, adds additional mineralogical interest and is often appreciated by collectors for its rich green color, rarity, and association with classic phosphate specimens.
