About this specimen

Bright brass pyrite crystals combine cubic and dodecahedral-looking faces across a dark marmatite-bearing matrix from Nandan. Several larger metallic forms dominate the center, while slender darker crystals and smaller pyrite faces project around the edges. The second view reveals the layered depth of the group and a narrow black base. Contrasting golden planes and iron-rich sphalerite create a compact association with strongly varied metallic tones. Dimensions: 3.1 × 1.5 × 2.5 cm / 31 × 15 × 25 mm / 1.22 × 0.59 × 0.98 inch. Estimated weight: 13 g / 0.46 oz, calculated from its dimensions.
