Vivianite is a hydrated iron phosphate mineral that can occur as colorless, green, and blue. It crystallizes in the monoclinic system. While it can be found in a variety of geological environments, its quality can vary significantly. For example, high-caliber crystals larger than 2 cm are only recovered sporadically, and from just a few places on earth. The top localities for the species include Bolivia, Romania, and Brazil. This is an attractive example with multiple, elongated, tabular vivianite crystals that are intergrown at their sides. The crystals have formed at varying lengths and at slight angles, creating a cool, reticulated structure that resembles a network of towers. The vivid, deep-green tone, glossy luster, and translucency of the crystals gives them a gem like beauty. When light passes through the vivianite crystals, the specimen resembles an emerald palace suspended along a cliff.​​​​​​​
