Strashimirite specimens for sale

Strashimirite is a hydrated copper arsenate mineral with the formula Cu8(AsO4)4(OH)4·5(H2O). It forms as small, tabular to fibrous crystals that can display a radiating habit, often presenting a greasy to silky luster and a pale to mid-green color, sometimes pale white. The mineral is typically translucent with a green streak and a Mohs hardness around 2.5–3, making it relatively soft and easy to scratch compared with many silicate minerals. Habits range from delicate clusters to compact aggregates, frequently appearing as tabular plates or slender fibres that reflect light in subtle ways. Its composition and hydration give it a distinctive appearance in hand specimens and collections, especially where hydrated copper phosphates are sought after.
