Spangolite with Brochantite and Malachite – Mex-Tex Mine, Bingham, New Mexico, USA
 
Lustrous blue-green Spangolite crystals to 1 mm on vuggy Quartz matrix, with green Brochantite and Malachite in association. The rare copper/aluminium-sulphate Spangolite is regarded as a coveted „signature species“ for the Bingham mining district (cf. LAPIS-Steckbrief 7-8/2019). Pretty miniature specimen from a classic dump recovery (1991)
