Peacock Ore Chalcopyrite Bornite Norway Natural Mineral Specimen Collectors Display Piece with Certificate of Authenticity
£ 12.60
Peacock Ore (Chalcopyrite/Bornite) – Norwegian Mineral SpecimenThis vibrant Peacock Ore specimen from Norway is a visually striking mineral,
celebrated for its intense iridescent colours and metallic lustre. Carefully selected for its bold appearance and natural character, this piece displays a stunning array of shifting hues including deep blues, purples, golds, and greens. The surface exhibits the classic “peacock” effect, making it a highly decorative and desirable specimen for collectors and display.Mineral Identification and CompositionPeacock Ore is a trade name commonly applied to copper iron sulfide minerals such as chalcopyrite (CuFeS₂) or bornite (Cu₅FeS₄), both of which can display vivid iridescence. The striking colours are typically the result of natural oxidation processes on the surface, where thin films of copper oxides interact with light to produce the characteristic rainbow effect. Chalcopyrite crystallises in the tetragonal system, while bornite is orthorhombic, though specimens are often found in massive or granular forms rather than well-defined crystals.Colouration and Surface FeaturesThe most distinctive feature of this specimen is its brilliant metallic sheen combined with multi-coloured iridescence. The surface may display a dynamic blend of electric blue, violet, magenta, and golden tones, which can shift depending on the angle of light. This effect is caused by light interference within the oxidised surface layer, creating a natural spectrum-like appearance. Texturally, the specimen may exhibit a rough, crystalline, or botryoidal surface, adding depth and complexity to its visual presentation.Geological Formation and OriginChalcopyrite and bornite typically form in hydrothermal environments, where mineral-rich fluids circulate through fractures in the Earth’s crust and deposit sulfide minerals as they cool. These minerals are commonly associated with copper ore deposits and are often found alongside other sulfides such as pyrite and galena. Norwegian mineral localities are known for producing high-quality sulfide specimens, shaped by ancient geological processes involving volcanic and tectonic activity.Crystal Habit and StructureWhile well-formed crystals of chalcopyrite and bornite do occur, Peacock Ore specimens are most often presented as massive aggregates or irregular formations. The internal structure is crystalline, though external crystal faces may not always be sharply defined. Natural fractures, grain boundaries, and metallic textures are typical and contribute to the authenticity and geological significance of the piece.Collecting and Display AppealPeacock Ore is highly sought after for its vivid colours and eye-catching appearance. It is an excellent addition to any mineral collection, particularly for those interested in sulfide minerals or visually striking specimens. This piece is ideal for display in a cabinet, on a shelf, or as a focal decorative item. Its natural iridescence ensures it stands out in any setting, making it suitable for both collectors and interior display purposes.Authenticity and GuaranteeThis crystal is a genuine natural specimen and includes a Certificate of Authenticity lifetime guarantee card, providing confidence in its origin and mineral classification. The photograph shown is of the exact specimen you will receive, ensuring complete transparency and satisfaction.Size and Natural ConditionPlease refer to the photo for full sizing and scale. As a natural mineral specimen, variations in surface texture, colour distribution, and minor imperfections are expected and enhance the individuality and authenticity of the piece.
