Vivianite is a hydrated iron phosphate mineral admired for its gemlike crystal forms and intense coloration, which can range from deep blue to rich forest green. Fine crystals are uncommon, and sharply terminated examples with strong transparency are particularly sought after by collectors. When well preserved, vivianite offers a rare combination of dramatic color, clarity, and elegant crystallography.
This striking specimen originates from the Rosia Poieni Mine, a locality known for producing some of the finest vivianite crystals in Europe. This example features a sizeable crystal that displays excellent prismatic form with a sharp termination and a richly saturated green color. Lustrous, translucent, and vibrant, the piece illuminates beautifully, evoking stained glass, while its balanced composition lends it a strong visual presence. Together, these qualities place the specimen among the most refined examples of vivianite from this important Romanian locality.
