Adamite

A fabulous top shelf adamite specimen with dense coverage by spherical aggregates colored a gorgeous greenish yellow. There are clusters of small white optic clear calcites on select areas. A neat vug in the back that shows well on its own!  The specimen was formally in the David Stroud collection.
