Pyroxene crystals in 3D

In the summit area of Stromboli one can find beautiful pyroxene crystals. Specimens up to 15mm in size are mixed with other loose material. Fresh crystals are shiny black, older ones get weathered and are grey and less shiny.

Above, from left to right: typical single crystal with a short prism; crystal with a longer prism; twin crystal; quadruple twin (such 'miniature crosses' are quite commonly found on Stromboli).
