7.1 x 6.7 x 3.4 cm
Hardystonite: Ca2ZnSi2O7 , Clinoherdite: CaZnSiO4·H2O
This specimen exhibits 4 different colors under SW UV. The Hardystonite is blue/violet, the Calcite is red/orange, the Clinoderdite is yellow/orange and the Willemite is bright green (the green in the pictures is over exposed because it fluoresces more vividly than the other minerals - it is also a richer green). The Hardystonite is more vivid than most specimens (the pictures are quite realistic). The Clinoherdite is an alteration of the Hardystonite.
Flaws: Essentially massive material.
