Rudny, in Kazakhstan’s Kostanay Region, is a major iron-mining center whose extensive deposits have also produced a diverse assemblage of collectible mineral crystals. The principal localities, particularly the Sokolovskoe Iron Mine and Sarbai Deposit, have yielded quartz—including amethyst, chalcedony, and agate—as well as calcite, siderite, fluorite, and a range of zeolites and related silicates. Rather than representing a conventional gemstone-mining industry, crystal production at Rudny has largely resulted from the excavation of iron and polymetallic ores, with well-developed crystals recovered from cavities, veins, and altered zones exposed during mining. The district is particularly significant to mineral collectors for its amethyst, zeolite-group minerals, and unusual silver-bearing mineral assemblages from Sarbai, making specimens from Rudny an important by-product of Kazakhstan’s long-established metallurgical mining industry.
This specimen is a bed of lustrous calcite crystals! A gentle coloring of yellow accents the gleaming calcites. Perfect example! Accompanied by an old Rocksmith’s label.
