Shattuckite / Planchéite with Malachite - NKO 015

Handsize botryoidal planchéite / shattuckite with two malachite crystals








Measurements:  125 x 97 x 55 mm

Description:  A delicate specimen consisting of botryoidal planchéite / shattuckite with two malachite crystals, with a conglomerate matrix of planchéite / shattuckite, quartz and malachite.

It is obvious that this specimen was removed fairly close to the surface, as it has a few small plant roots embedded in its base (photograph bottom, left).

The specimen, which displays well on a flat surface, has some damage to the malachite and to the edges. A small part was cut /trimmed at the top, probably to remove unwanted matter (see image bottom right, close to centre of photograph).
