A diverse and visually striking collection of natural raw minerals, stones, and crystals, formed through a volcanic–hydrothermal geological system. This lot includes a broad variety of silica, carbonate, sulfate, and volcanic specimens, showcasing different textures, colors, and crystal habits. Included minerals (identified): Calcite – massive, banded, fibrous and crystalline varieties Milky Quartz – rough and vein quartz pieces Drusy / crystalline Quartz – quartz crystal pockets and vugs in volcanic matrix Chert / Flint (chalcedony) – microcrystalline quartz with conchoidal fracture Jasper – iron-rich brown and red jasper with quartz veining Selenite (Satin Spar – gypsum) – fibrous, silky crystalline forms Vesicular Basalt / Volcanic Scoria – gas-bubble volcanic lava rock Altered volcanic host rocks with iron-oxide staining Minor pyrite inclusions visible in some quartz cavities Geological context: These specimens represent different stages of geological formation: Volcanic activity (basalt/scoria) Hydrothermal fluid circulation, depositing quartz, calcite, gypsum Silica replacement and alteration, forming jasper, chert, chalcedony Iron-rich environments, producing red, brown, and yellow staining Some calcite- and quartz-bearing pieces show mild pink, orange, or red fluorescence under UV light, caused by natural trace elements such as manganese and iron. Weight: Total weight: approx. 4223 g Size: Various sizes (Please see images with measuring tape for scale) Condition: Natural, unpolished, untreated specimens As found, with natural fractures, cavities, and surface textures --- Metaphysical Properties (for collectors & crystal enthusiasts) Quartz: Amplification, clarity, energy cleansing, balance Calcite: Emotional healing, mental clarity, positive energy flow Jasper: Grounding, stability, protection, strength Chert / Chalcedony: Focus, calmness, communication Selenite (Satin Spar): Energy cleansing, spiritual clarity, calm environments Basalt / Volcanic rock: Grounding, transformation, connection to Earth energy Pyrite: Protection, confidence, manifestation, abundance --- Perfect for: Mineral and rock collectors Geological study and teaching specimens Display or decorative natural collections Crystal and metaphysical enthusiasts Curation into smaller themed lots A rich, educational, and authentic natural mineral collection, offering both scientific and aesthetic value.
