Description

An intergrown mass of transparent, bright yellow willemite crystals associated with fans of very pale pink elongated smithsonite crystals (to 2 mm) and pseudo-octahedral crystals of pale-green zincolivenite (?). A tiny fragment of sulphide matrix is attached to the zincolivenite.


The willemite does not fluoresce under either short, medium or long wavelength UV radiation.


The specimen was acquired from Mineral Kingdom (Julius Zweibel) in December 1989.
