Cu5Zn(AsO4)2(OH)6 · H2O
Colour:
Bright emerald-green
Lustre:
Vitreous
Hardness:
3½

Name:
Goldhillite is named after its type locality, the Gold Hill mine, Tooele County, Utah, USA.
The As analogue of kipushite (full analogy) and philipsburgite ("partial" analogy because of As-P ordering in the crystal structure).
Chemically similar to sabelliite, theisite, veselovskýite, and (to some extent) to zincolivenite.
