Hornblende specimens for sale

Hornblende is a common amphibole mineral that forms in dark green to black crystals with a characteristic elongated, prismatic habit and a vitreous to silky lustre. It often occurs in foliated to granular metamorphic rocks and intrusive igneous environments, where it can appear as slender prisms or as intergrown masses that reflect light with a subtle sheen. Colors range from deep green to brownish hues, and twinning or acicular aggregates are frequently observed in hand specimens. Notable localities include Norway, Iran, Germany, the USA, and Myanmar, where hornblende occurs in a variety of rock types, from granulites to schists and diorites, sometimes forming sizable, well-formed crystals suitable for display.
