Colorless, long, bladed crystals in slightly divergent group to 4mm. Nordenskioeldine is a rare tin borate occuring in 12 worldwide localities, which includes four in China and only one in the USA. It was first pubublished in 1887, so you would have to think it is overlooked or has a very narrow set of conditions in which to form. ID by Dr. Igor Pekov.
