Chalcanthite Specimen | 108mm | Anthropogenic Limonite It sits atop a base

It sits atop a base of granular white quartz matrix

giving it a satisfying shape

but avoid prolonged exposure to water to prevent structural weakening

Chalcanthite Specimen | 108mm | Anthropogenic Limonite It sits atop a baseA vivid example of anthropogenic chalcanthite copper sulphate crystals grown through industrial or mining processes rather than natural geological formation, making each specimen a striking intersection of chemistry and colour. The front face is densely encrusted with rosette clusters of deep cobalt and electric blue chalcanthite crystals, their bladed, fan like formations catching light with an almost metallic shimmer. Turquoise green malachite coats
