Quite old German specimen of Wavellite spheres on slate matrix. The balls of Wavellite are up to 1.4 CM across are translucent and most have a amber brown color. A few broken spheres show the radial structures well and the color of those is a golden greenish hue. A few tiny spheres are nearly black as well. This is a choice piece that has been in the USA for over 60 years, (ex TL Baskin and Dick Hauck with old labels) but is probably far older. The slate outcrops of the Langenstriegis were productive in the mid to late 1800's and these classics are almost never seen on this side of the Atlantic.
