4.6 x 3.4 x 2.0 cm. A showy specimen, richly covered with sparkly, dark green microcrystals of herbertsmithite, an ultra rare copper, zinc halide from near the type locality in Chile. The light blue chrysocolla nicely compliments this UNUSUALLY RICH and fine piece.

The other cations mentioned behave similarly, producing stabilized rhombohedral paratacamites and end-members analogous to herbertsmithite, which if found in nature, as the Ni analogue has been, should be named species.

The odd thing about herbertsmithite is that the electrons are arranged in a triangular pattern (a Kagome lattice), meaning that electrons are forced to spin against one another, rather than the more normal pattern of spinning with their neighbours.

Two kagome compounds, volborthite Cu3V2O7(OH)2·2H2O and herbertsmithite ZnCu3(OH)6Cl2, are compared in order to derive information about the intrinsic properties of the spin-1/2 kagome antiferromagnet.
