Prehnite after laumontite
description: <p style="text-align: justify;">LOCALITY: Mumbai area, India <br /><br />5 1/2" Across <br /> <br />This piece consist of a cluster of prehnite pseudomorphs after laumontite. In the genesis of this piece, the prehnite crystals first encrusted the earlier formed laumontite crystals. The latter species was then dissolved to result in the hollow prehnite pseudomorphs. This piece was bought from Mike Keim of Marin Mineral, California in late 2017. It is a good representative specimen. <br /><br />Photo by Matthew Webb of Melbourne, Victoria, Australia</p>
