The photograph shown represents an example of the actual specimen you will receive. Each piece is carefully selected for its deep black colour, strong metallic character, and collector quality. Your specimen includes a Certificate of Authenticity lifetime guarantee generic card, confirming it is a 100% genuine natural mineral. Please refer to the photographs for full sizing and scale. Mineral Species & Chemical Composition Magnetite is an iron oxide mineral with the chemical formula Fe₃O₄. It belongs to the oxide mineral group and crystallises in the isometric (cubic) crystal system. It is one of the most important and widely studied iron minerals due to its abundance, magnetic properties, and geological significance. Key mineral data: Mineral Species: Magnetite Chemical Formula: Fe₃O₄ Mineral Group: Oxide Crystal System: Isometric (Cubic) Hardness: 5.5–6.5 on the Mohs scale Lustre: Metallic to submetallic Colour: Deep black to iron-grey Transparency: Opaque Streak: Black Magnetite is well known for its natural magnetic behaviour, a result of the arrangement of iron ions within its crystal lattice. Arendal Locality & Geological Context Arendal, in Aust-Agder, Norway, is a historically significant mineral locality known for complex Precambrian geological formations. The region features ancient metamorphic and igneous rocks that host a variety of iron oxide and silicate minerals. Magnetite from Arendal typically forms within: Metamorphic iron-rich zones Skarn environments Pegmatitic and igneous intrusions High-grade metamorphic terrains These geological conditions allow well-developed magnetite crystals and massive formations to form over immense geological timescales. Associated minerals from the region may include: Quartz Feldspar Amphibole Garnet Other iron oxides such as hematite Norwegian magnetite is respected among collectors for its dense, pure appearance and strong mineral character. Appearance & Crystal Habit This pure black magnetite specimen displays the classic characteristics of high-quality iron oxide: Rich, uniform black colouring Metallic to slightly reflective surfaces Dense, weighty feel relative to size Natural crystalline or massive structure Magnetite commonly forms cubic or octahedral crystals, though some specimens appear in compact or granular aggregates depending on formation conditions. The “pure black” description reflects its deep, consistent colour without significant alteration or weathering tones. Each specimen is natural and untreated, preserving its authentic geological features. Size & Collector Appeal (35–60mm) At approximately 35–60mm, this is a substantial display specimen suitable for: Mineral and crystal collections Iron oxide reference collections Educational geology displays Cabinet specimen arrangements Gifts for serious mineral enthusiasts Its bold black appearance makes it visually striking when displayed alongside lighter-coloured minerals. Scientific & Historical Importance Magnetite plays a crucial role in geology and Earth sciences. It is used in paleomagnetic research to study the historical orientation of Earth’s magnetic field, as magnetite grains can record magnetic alignment at the time of rock formation. Historically, naturally magnetised magnetite (lodestone) was used in early navigation compasses, highlighting its long-standing scientific significance. In spiritual traditions, magnetite is sometimes traditionally associated with attraction symbolism; however, this listing presents it strictly as a natural mineral specimen valued for geological and collector interest.
