印度 紅寶石 黄铁矿 闪锌矿
Corundum (Variety: Ruby) with Pyrite and Sphalerite
刚玉（红宝石品种）伴黄铁矿和闪锌矿
English Description
Minerals: Corundum (Variety: Ruby) – Al₂O₃, Pyrite – FeS₂, Sphalerite – ZnS
Locality: Madikeri area, Kodagu District, Karnataka, India
Dimensions: 10.90 cm x 6.50 cm x 5.45 cm
Weight: 430 grams
Description: This specimen features a well-formed ruby crystal embedded in a matrix of pyrite and sphalerite. The deep red hue of the ruby contrasts strikingly with the metallic luster of pyrite and the resinous luster of sphalerite. Such mineral associations are indicative of high-temperature hydrothermal environments where aluminum-rich fluids interact with sulfur-bearing minerals. The presence of pyrite and sphalerite suggests the involvement of iron and zinc in the mineralizing process, contributing to the unique assemblage observed in this specimen.
