Mineral (Man Modified)

Quartz

Quartz (SiO₂ - Silicon Dioxide)

Quartz

Quartz (SiO₂)

Basalt

Mafic volcanic rock, primarily composed of Plagioclase, Pyroxene, and Olivine

Labradorite (likely Black Labradorite or Larvikite)

Labradorite (Na,Ca)(Al,Si)4O8. If a rock, it is typically anorthosite, gabbro, or norite, or a variety of syenite called Larvikite if it is specifically from Larvik, Norway.

Slate

Slate (a fine-grained, foliated metamorphic rock). Mineral composition: Primarily composed of mica minerals (muscovite, chlorite, sericite) and quartz, with minor amounts of hematite, pyrite, and other accessory minerals.

Sandstone (likely a river or beach pebble)

Sandstone (a clastic sedimentary rock)

Iron Ore / Ironstone Concretion

Mixture of iron oxide/hydroxide minerals, likely some combination of Hematite (Fe2O3), Goethite (α-FeOOH), and Limonite (a general term for hydrated iron oxides of variable composition) or potentially Bauxite (a mixture of aluminum hydroxides, often with iron oxides, (Al(OH)3) and FeO(OH)). The visual characteristics strongly suggest iron-rich material.

Serpentine Schist with Quartz Vein

Serpentine Schist (a type of Metamorphic rock). The white band is likely Quartz (SiO2).

Clear Quartz (beads in a bracelet)

Quartz (SiO2)

Jasper (yellow/cream variety)

SiO₂ (Cryptocrystalline Quartz)

Milky Quartz

Quartz (SiO2)

Unknown Organic Object (likely a berry or fruit)

Not applicable; this is not a geological specimen. If it were a cranberry, its scientific name would be Vaccinium macrocarpon; if a cherry, it would be Prunus avium or Prunus cerasus.

Jade

Jadeite or Nephrite

Scoria

Scoria (a vesicular basalt or andesite)

Marble

Marble (primarily Calcite, CaCO3 or Dolomite, CaMg(CO3)2)

Lazulite

Lazulite (Mg,Fe2+)Al2(PO4)2(OH)2

Pink Stained Rock (Likely Quartzite or Sandstone with Iron Oxide Staining)

Quartzite (metamorphic) or Sandstone (sedimentary); coloration likely due to hematite or other iron oxides.

Gneiss

Gneiss (a metamorphic rock)

Granite Pegmatite

Coarse-grained Granite (SiO2 - Aluminum and Alkalies)

Himalayan Salt

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

Gneiss (likely)

Gneiss

Banded Gneiss (with possible weathered sulfide or iron staining)

Gneiss, potentially with iron oxide/hydroxide staining (e.g., limonite) or weathered sulfides

Chert (often referred to as 'Jasper' when red)

Chert (microcrystalline quartz, SiO₂)

Greisen

Greisen

Jade

Jadeite or Nephrite (both are commonly referred to as 'jade'). Jadeite: NaAlSi2O6; Nephrite: Ca2(Mg,Fe)5Si8O22(OH)2.

Dark-colored Igneous Rock (likely Basalt or Diabase)

Basalt (extrusive igneous) or Diabase (intrusive igneous)

Quartz with Mica inclusion

Silicon Dioxide (SiO2) with Muscovite/Biotite inclusions

Unidentified Rock Fragment

Unknown

Jade

Jade can refer to two distinct minerals: Nephrite (a variety of the mineral actinolite, Ca2(Mg,Fe)5Si8O22(OH)2) and Jadeite (Na(Al,Fe3+)Si2O6). Based on the image, showing a relatively uniform green color and possibly slight translucence in bead form, it is very likely one of these, but determining which one from a photo is difficult without specific testing.

Micaceous Rock (likely Muscovite Schist/Gneiss or a Muscovite-rich Specimen)

Predominantly Muscovite (KAl2(AlSi3O10)(F,OH)2), often found in rocks like Muscovite Schist or Muscovite Gneiss.

Basalt with Vesicular Surface

Basalt (Mafic Extrusive)

N/A (Non-Geological Object)

Veined Pebble (likely a Quartz-Veined Pebble)

Pebble with Mineral Vein (e.g., Quartz Vein in a Chert/Mudstone Pebble)

Chert (Flint)

Chert (predominantly SiO₂ - silicon dioxide)

Basalt

Basalt

Sandstone with Magnetite and Iron Staining

Clastic Sedimentary Rock (contains Fe3O4 and Limonite/Hematite)

Nephrite Jade
