Pentagonite (rare)

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 so the habit of the crystals is different. Pentagonite gets its name due to the fact that the crystals form in unusual 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 Wagholi Quarry in the Deccan Trap 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, radiating, crystallized, "burst"-like intense neon blue aggregates of Pentagonite sitting on matrix. The largest group of Pentagonite measures 1.5 cm across. There are a few tiny imperfections that can be seen, so the piece is not 100% pristine, but it's still excellent condition, and that color is outstanding. A very showy and specimen of this extremely rare (and underappreciated) material. These specimens represent the best of the species, and eventually will no longer be found
