Blue Chalcedony Botryoidal Aggregate and White Mordenite — Pune, India | 40 g | 6 × 7 × 4 cm

Blue Chalcedony with White Mordenite — Natural Indian Mineral Specimen

This attractive natural mineral specimen features blue Chalcedony beautifully associated with white Mordenite, a distinctive and collectible mineral combination from India. Blue Chalcedony forms the sculptural base, often developing rounded, botryoidal, stalactitic, or irregular silica-rich structures, while the fine white Mordenite grows over the Chalcedony to create a striking contrast of blue and white.

This association is particularly well documented from Maharashtra, India, where blue Chalcedony and white Mordenite occur together in basalt-hosted cavities. Mineral references describe these specimens as blue Chalcedony structures covered by snow-white Mordenite sprays, fibers, or spherical aggregates.

The specimen measures approximately 6 × 7 × 4 cm and weighs approximately 40 grams, making it a compact collector-size piece suitable for a mineral cabinet, zeolite collection, geological display, or natural mineral collection.

Natural variations in color, crystal development, luster, inclusions, surface texture, cavities, contact areas, and minor imperfections are part of the specimen's geological character.
