Quartzite

Quartzite (primarily SiO2)

Organic Material (likely a fruit or berry)

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.

Greenstone (Greenschist)

Greenschist (composed of Chlorite, Epidote, and Actinolite)

Almandine Garnet

Almandine - Fe3Al2(SiO4)3

Gneiss

Quartz (Crystal/Druzy Quartz)

Quartz (SiO₂)

Serpentinite

Chert Conglomerate (or Breccia)

Sedimentary Clastic Rock (variety: Ferruginous Chert Breccia)

sedimentary

Moonstone

Adularia (orthoclase) or Albite (plagioclase), a potassium aluminum silicate of the feldspar group

Pyrite

Iron Sulfide (FeS2)

Marble

Marbles are primarily composed of calcite (calcium carbonate, CaCO3) or dolomite (calcium magnesium carbonate, CaMg(CO3)2).

Metamorphic Rock

Smoky Quartz

Silicon Dioxide (SiO2)

Diopside (likely Chromian Diopside)

Diopside, part of Clinopyroxene family of inosilicates. Chemical formula: CaMgSi2O6. The green variety is often Chromian Diopside due to chromium impurities.
