Exceptional  combo specimen of Ludlamite and Vivianite decorated by Siderite.  It displays superb 55 mm tabular crystal of Vivianite. It is partially doubly terminated. The Vivianite has intense dark-green color, vitreous luster, sharp shape and strong transparency and gemminess. The rare iron phosphate Ludlamite forms thin plates of parallel elongated crystals penetrating among the Vivianite crystal. The Ludlamite has brighter green color, good gemminess and luster.  Than colored botryoidal Siderite clusters add a nice contrast. Some small nicks and right side contact. On acrylic base.

Outstanding!
