This specimen is covered with velvety malachite. On that are found lustrous crystals of azurite and yellowish iodargyrite as crystalline masses with crystals to 1 mm.

  

This specimen is host to one of the largest masses of iodargyrite that I can recall seeing. It is completely crystalline with individual crystals to over 0.5 cm across. The mass in the center is 4 cm across its longest dimension. Scattered on the surface of the iodargyrite are micro crystals of either embolite or chlorargyrite. Iodargyrite displays color change between incandescent and fluorescent lighting. It is a drab color under incandescent lights and bright lemon yellow under fluorescent lights.

Origin: Broken Hill, New South Wales, Australia

Sample size: 5.4 x 4 x 3.4 cm (top/2nd/3rd row), 8.5 x 4.6 x 4 cm (4th/bottom row)
