Serpentinite

Serpentinite; chiefly serpentine-group minerals (antigorite, lizardite, chrysotile), commonly with magnetite and minor chromite

Serpentine

Antigorite / Lizardite / Chrysotile (Mg, Fe, Ni, Al, Zn, Mn)2-3(Si, Al, Fe)2O5(OH)4

Metal Alloy (Likely Pewter or Sterling Silver)

Not a natural geological specimen; composed of refined metals. If pewter, it's a tin-based alloy. If sterling silver, it's 92.5% silver and 7.5% other metals (usually copper).

Serpentinite (probable)

Serpentinite; chiefly serpentine-group minerals (antigorite, lizardite, chrysotile), commonly with magnetite and relict olivine/pyroxene

Serpentinite

Serpentinite (composed primarily of serpentine group minerals like lizardite, chrysotile, or antigorite; Mg3Si2O5(OH)4)

Jade

There are two distinct minerals classified as Jade: Jadeite (Na(Al,Fe3+)Si2O6) and Nephrite (Ca2(Mg,Fe)5Si8O22(OH)2). Based on the image showing translucent, somewhat fibrous material, it is likely Nephrite.

Cinnabar (HgS)

Serpentine

Serpentine group minerals (e.g., Antigorite, Chrysotile, Lizardite). Chemical formula: (Mg, Fe)₃Si₂O₅(OH)₄

Serpentinite

Serpentinite (Mg, Fe, Ni)₃Si₂O―(OH)₄

Serpentine Jade (New Jade/Olive Jade)

Serpentinite (a rock composed primarily of serpentine minerals) / Mg3Si2O5(OH)4 for Antigorite and Lizardite

Himalayan Salt

Halite (mineral name), chemical formula NaCl (sodium chloride). Generally, 'Himalayan Salt' is a trade name for evaporite minerals from specific regions.

Magnetic Hematite

Magnetized Hematite (an iron oxide mineral, Fe2O3, that has undergone magnetization)

Serpentinite

Serpentinite

Serpentinite (Serpentine Rock)

Serpentinite is a rock composed of one or more serpentine group minerals, chiefly antigorite, chrysotile, and lizardite, with the general formula (Mg,Fe)3Si2O5(OH)4. Often includes other minerals like magnetite, talc, and chromite.

Galena

Galena (Lead Sulfide), PbS

Serpentinite

Serpentinite (composed primarily of serpentine-group minerals like antigorite, chrysotile, and lizardite; chemical formula varies but generally Mg3Si2O5(OH)4)

Serpentinite (Serpentine Rock)

Primarily composed of serpentine group minerals, such as antigorite, chrysotile, and lizardite. Chemical formula for serpentine minerals is (Mg,Fe)3Si2O5(OH)4.
