Shandite is a sulfide mineral with chemical formula: Ni3Pb2S2. It was discovered in 1948 by the German mineralogist Paul Raumdohr who named it named after Scottish petrologist, Samuel James Shand (1882–1957). Ramdohr characterized shandite by its metallic luster and a brass-yellow color. It has a specific gravity of 8.92, and a Mohs hardness value of 4. Shandite is commonly found as an inclusion in other minerals such as Heazelwoodite Ni3S2 or serpentine.

- Shandit ist ein selten vorkommendes Mineral aus der Mineralklasse der „Sulfide und Sulfosalze“ mit der chemischen Zusammensetzung Ni3Pb2S2 und damit chemisch gesehen Nickel-Blei-Sulfid. Shandit kristallisiert im trigonalen Kristallsystem, konnte bisher allerdings nur in Form winziger, meist in Serpentin eingebetteter Körner sowie orientiert verwachsen mit anderen Sulfiden oder dünne Ränder um diese bildend gefunden werden. Das Mineral ist in jeder Form undurchsichtig (opak) und zeigt auf den messinggelben, auf polierten Flächen auch cremeweißen, Oberflächen einen metallischen Glanz.

- Shandite is a sulfide mineral with chemical formula: Ni3Pb2S2. It was discovered in 1948 by the German mineralogist Paul Raumdohr who named it named after Scottish petrologist, Samuel James Shand (1882–1957). Ramdohr characterized shandite by its metallic luster and a brass-yellow color. It has a specific gravity of 8.92, and a Mohs hardness value of 4. Shandite is commonly found as an inclusion in other minerals such as Heazelwoodite Ni3S2 or serpentine. Its crystal system is trigonal hexagonal scalenohedral with symbol 32/m. It belongs to the space group R3m. Shandite is an anisotropic mineral, which means it has different properties when being viewed from different directions. In cross-polarized light it appears as gray blue or yellow-brown colors. It also has very distinct relief, which means it stands out against its mounting medium and can be easily seen. It has an index of refraction of 1.54, which is the measure of the speed of light through the substance. In plane polarized light, shandite has a creamy white color and distinct pleochroism, which is the property that makes it appear to be different colors at different angles. It has strong birefringence, which is the decomposition of light into two rays, and appears dark blue and gray. In subsequent decades several compounds with shandite type structure were synthesized by several chemists. The group of compounds M3A2Ch2 with shandite type crystal structures was subsequently called "shandites". They include Co3Sn2S2 = Sn2Co3S2 = Co3/2SnS that became famous in recent years as layered half metal ferromagnet and topological semi metal including kagome layers of cobalt atoms. (en)
