Richterite is a layered silicate mineral that forms in amphibole-group structures, commonly presenting elongated prismatic crystals with a glassy to satin lustre. The color ranges from pale to greenish or brownish tones, often showing a light to medium translucence depending on the specimen. Habit varies from slender needles to firm, course prisms, and it can occur in aggregates that emphasize their elongated, striated faces.

About Richterite
Notable specimens come from classic locales such as Canada and Madagascar, with other important collections reporting finds in Afghanistan, Sweden, and Brazil. Richtersite-bearing rocks typically form in metamorphosed ophiolitic and skarn environments, where high-temperature, low-pressure conditions promote amphibole crystallization. The mineral is commonly associated with other amphiboles and silicate minerals in mineral-rich veins and contact metamorphic zones, yielding specimens that display precise crystallography and a pleasing, gleaming surface.
Collectors value richterite for its crisp crystal forms, subtle coloration, and the way light interacts with its prismatic faces. The species adds diversity to amphibole suites, offering a window into the geologic processes of the environments where it grows and the aesthetic appeal of its elongated habit when displayed with complementary minerals.
