AEGIRINE SPECIMENS

Aegirine is a striking, dark green to black pyroxene mineral known for its elongated, prismatic crystals with a sharp, spear-like appearance. This sodium iron silicate often displays a vitreous to submetallic luster, giving it a sleek, glossy finish that enhances its appeal to collectors. Aegirine commonly forms in alkaline igneous rocks, such as nepheline syenites and phonolites, and is often found in association with minerals like feldspar, nepheline, and riebeckite. Its crystals may exhibit unique terminations, and some specimens can show iridescent colors when viewed under direct light. Aegirine's intense, almost opaque green or black coloration makes it a captivating addition to mineral collections, and it is particularly prized for its distinct crystal habit and deep, moody hues.
