Bright Orange octahedral crystal with cubic faces to nearly 2mm on shiny black Ilvaite crystals with waterclear Fluorite and possible brown feathery Rhodochrosite. Natanite is a rare oxide of tin and found in less than 15 places worldwide. There are no US localities. Of course there are no economic deposits of tin in the US either, so not a whole lot of occurences of tin mineralization.
