At first glance, one may think that this is a smithsonite specimen, with dozens of blue-green bulbous formations on a heavy hematite/goethite matrix. Closer examination will reveal that each "blob" is a small, radiating cluster of semitransparent Cuproadamite crystals. Each cluster averages 1/8 inch in diameter, and contains crystals that are much too large to produce the silky, "melted wax" sheen of smithsonite. In a few places, the clusters are packed closely enough to intersect, making small areas that are coated with crusts of the mineral. Their color is unusual and splendid, with the dark, rust-brown of the matrix adding the perfect backdrop. Do you have one of these??
