This is definitely the best Vivianite specimen I have ever offered on my site. It has super gemmy emerald green crystals (to 2.2x0.8 cm) aesthetically arranged by nature on a Siderite matrix - much better than the more common, fragile Limonite material. The Vivianite crystals are in pristine condition with nice accenting dotting of Siderite crystals on some of the terminations. A Beauty !!!
