Composite, bladed azurite crystals (to 40 mm), showing parallel growth, are closely intergrown to form a stellate nodule, or "azurite rose".  The azurite surfaces are quite lustrous in places, while others have an etched appearance, which greatly enhances the colour intensity.

These azurite nodeules were found in considerable abundance, embedded in a white kaolinitic clay, (which has been removed by mechanical means); the azurite is assumed to have grown authigenically in the clay matrix.

The specimen is from 5 Level, and was recovered during a specimen mining campaign in the upper levels during 2000 and 2001, led by Ian Bruce, Dave Lloyd, and Simon Brock (see Cook et al., 2002).
