Grenville, Uvite ps Serendibite, Portage du Fort, Quebec

Recently, some unusual pseudomorphs of uvite after serendibite have been collected near Portage du Fort, Pontiac County, Quebec. The crystals are, generally a light blue-grey and usually have a core of serendibite. Sometimes, only a thin rim of uvite is present on the serendibite, other times the crystals are solid uvite, sometimes with a little spinel. These unusual pseudomorphs are associated with white diopside crystals and a brownish phlogopite. Unusual!

  • A nice, 12mm pseudomorph of uvite after serendibite is present on the left side of this specimen, surrounded on the edges by epitactic phlogopite. On the other side of this plate of diopside crystals are two smaller crystals, also partially encrusted with phlogopite. Nice!

  • There are two uvite pseudomorphs after serendibite at the top of this specimen. Both of them have natural fractures through them that have been partially filled with diopside, phlogopite and a brownish, prismatic mineral that resembles a tourmaline group mineral. Interesting piece!
