In this specimen we can observe cookeite in pink tones. It is associated with eucryptite, a rare lithium aluminosilicate, and quartz. Eucriptite-quartz pseudomorphs were first discovered at this Australian mine in 1963, they are pale pink and, more rarely, dark glassy brown in color, and fluoresce reddish under shortwave ultraviolet light. Eucryptite is in the area indicated by the arrow.
