01 · The material
Natural History
Magnetite occurs in igneous and metamorphic rocks and iron deposits. Its presence does not establish one formation story for a whole rock.
02 · Observe
Under the Loupe
Magnetic response is useful but not exclusive to magnetite. Industrial material and mixtures can respond too.
03 · Ownership
Collect & Care
Keep specimens dry and protected from knocks. Keep strong magnetic pieces away from magnet-sensitive objects and follow device manufacturers’ guidance.
04 · The human story
History, Lore & Tradition
Documented history
“Lodestone” is used for naturally magnetized material. A magnetite label and a claim of permanent natural magnetization are different claims.
Sources & further reading
References are labeled by role. A source documenting a belief is not evidence of a medical or mineralogical effect. Reflection prompts are C&C editorial suggestions.
