Glaucocerinite - Sold

Glaucocerinite is a hydrated zinc aluminum sulfate. There is likely a minor copper content causing the blue color. Dittler and Koechlin (1932) named the mineral after the Greek words for pale color and waxiness, both of which aptly describing this piece as well. This mineral shows a concentric structure which is visible under magnification. Rare.
