Pentagonite (rare and fine)

Item Description

When it comes to rarities, most of the time, crystals are small and nondescript. In the case of a species like Pentagonite, the crystals are large, beautiful and the only specimens of note come from one place in the world. The species chemically is identical to Cavansite, but it is dimorphous in the fact that the habit of the crystals is different. Pentagonite gets its name due to the fact that the crystals form in unsual five-fold "pentagonal star" cyclic twins consisting of 5 individual crystals that loop creating a minor distortion of the crystal lattice. These 5-sided or 5-pointed crystals are incredibly rare in nature. For reference, here is a link to a photo of a closeup of a textbook twin of the material (https://i.pinimg.com/236x/07/ed/60/07ed60470bade3918ceff313f2d8a9d4--image-search-amber.jpg). As I mentioned, there is only one place in the world where display quality specimens of this rare calcium vanadium silicate are found, the Deccan Trappe in India. The combination of the electric intense blue color along with the unique shape / style of the crystals makes them a highly desirable rarity on the market. This piece features very attractive, branching, crystallized, almost "stalactitic" tendrils of beautiful, sharp, intense neon blue aggregates of Pentagonite nestled in a vug of crystallized off-white Heulandite blades on basalt matrix. The largest "arm" of Pentagonite measures 2.0 cm long. I can see one tiny imperfection near the base of the group, but otherwise it is in superb condition. A very showy and top quality specimen of this extremely rare (and underappreciated) material. These specimens represent the best of the species, and eventually will no longer be found. Priced at $2,500 in the inventory.
