Olive green thin sincosite crystals to 2mm. The Sincosite from Rasmussen rivals the Sincosite from my findat the Ross Hannibal in 1996. Although I think the Hannibal Sincosite is still better. The Rasmussen Sincosite, like the Ross Hannibal, covers the spectrum of green shades from bright green to dark green and some are even a golden brown to brass. The Phosphovanadylite is a shiny black and can be seen in a few photos. The operator does NOT allow collecting. These were collected by special permission only and the operator discourages outside inquiries and does not allow third-party collecting. There is a very limited supply.
