Pentagonite (and Cavansite) are well-known worldwide thanks to the fantastic specimens from Wagholi. Not only are the finest examples found at this locality, but they are also incredibly beautiful and highly displayable. The magnificent intense electric blue color is what draws the eye, but the superb crystallization makes them all the more enticing. 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 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.
This wonderful cabinet specimen features a pair of good quality, beautiful, sharp, neon blue aggregates of Pentagonite sitting on a thin layer of white Mordenite atop basalt matrix. The main group nestled deep within the central portion of the specimen is an eye-catching "spray" filled with superb crystals flaring out in every direction. The second group is actually the largest of the two, measuring 2.8 cm, but it's contacted on the edge where it was removed from the pocket wall. A very showy and good quality specimen of this rare material.
