This huge 1-kilo crystal is the largest of the species that I know of, in good form. It is in fact a slightly distorted octohedron, really quite more obvious in person as it is very 3-dimensional. It is NEARLY complete all around, with a few relatively insignificant contacts and dimples that do not detract much form the sheer impact of the size and form. It has a nice vitreous, wet-looking luster to it and so is much prettier than the dull, earthy pyrochlore we often see from this locality - in other words, its not just big, but of high quality as well. A significant rarity only recently released from a private collection! 10.1 x 10 x 10 cm
