"Turkey fat" Smithsonite

Item Description

Double your pleasure with two different forms of classic yellow, cadmium or greenockite-rich, "turkey fat" smithsonite on sculptural matrix from Rush. The more striking and rich yellow forms on the left are the classic smithsonite pseudomorphs after tabular dolomite crystals. The waxy luster, translucent botryoids on the right are goldenrod-yellow. The underlying matrix is granular metallic sphalerite. An excellent and unusual Rush smithsonite with two forms.
