Geikelite is a rare magnesium titanium oxide, found usually in microcrystals or masses. It is the magnesium analogue of Ilmenite. Here we have a huge mass of geikelite (perhaps a record on its own) about 3 inches in size with distinct big crystals over 1 cm in size embedded within it and displaying nicely on one face. It shows metallic luster and some sharp twinning. From what I can see on MINDAT, its off the charts - confirmed via communications with several collectors of rarities and the Royal Ontario Museum, of which nobody has seen remotely the like of this one. I am thus told that this may be the best known by several people I ran it by, and the locality is very old and now completely defunct in terms of specimen production (though the walls are apparently accessible, the quarry has been unworked since closure in 1968). The quarry was one of the more recent mining operations in the area, the majority of other workings having taken place between 1900-1935. Operations at Maxwell started 1942, ended 1968. I would like to relate that Dr. Mark Feinglos told me this is an order of magnitude better than his specimen, which he thought was pretty good already!
