Though quite small, this Brochantite thumbnail specimen has beautiful, deep green coloration and well-preserved botryoidal form. It occurs as fine, tiny crystals that formed round aggregates which are clustered together in a thin crust. The Brochantite has a beautiful, deep forest-green coloration and its aggregates have a sparkle that in some places resembles a silky sheen. Though individual crystals may be transparent, the aggregates that these have formed are opaque. Besides the Brochantite, there are several tiny, round clusters of acicular cyanotrichite crystals scattered about on one area of the specimen. Though a loupe or magnifier is needed to see them in detail, their bright-blue color and acicular, radiating habit is clearly visible to the naked eye. Besides these minerals, there is a small amount of limonite host rock on the specimen. The piece is affixed to a foam base that fits inside a plastic specimen box.
