The specimen is sawed on one side so I assume that it was analyzed. It originated with Cureton mineral dealership. They often analyze their specimens. Be as it may, it really doesn't fit the description as yellow plates, but rather contains compact platy brown crystals in the matrix.but it is a different locality for this rare tin mineral. Anyhow the price is right!
