Metamorphic Rock (For Both Nephrite And Jadeite)

Quartz Pebble

Silicon Dioxide (SiO2)

Shale or Argillite

Shale (sedimentary) / Argillite (metamorphic)

Tumbled green-blue stone, likely serpentine or chlorite-rich metamorphic rock

Serpentinite (mainly antigorite/lizardite; identification is image-based)

Greenstone / altered mafic rock

Likely chlorite–epidote–actinolite schist or altered basalt (greenstone); exact identification requires thin-section or chemical testing.

Serpentine (possibly New Jade)

Serpentine group, Mg3Si2O5(OH)4

Likely slate (possibly phyllite)

Fine-grained, foliated metamorphic rock; mainly mica and chlorite, with quartz and feldspar

Citrine or Yellow Sapphire

Quartz (SiO2) or Corundum (Al2O3)

Jasper Agate (Carnelian Jasper)

Silicon Dioxide (SiO2) with iron oxide inclusions

Greenstone (Greywacke or Nephrite Jade variant)

Metamorphosed mafic igneous or sedimentary rock (e.g., Actinolite-Chlorite Schist)

Jadeite Jade

NaAlSi2O6 (Sodium Aluminum Silicate)

Serpentinized ultramafic rock (serpentinite)

Serpentinite, dominated by serpentine-group minerals (lizardite/chrysotile/antigorite), with possible magnetite, talc, and brucite

Green glass cabochon or tumbled stone

Indeterminate; likely man-made glass, possibly aventurine glass rather than a natural mineral

Serpentine

Serpentinite (complex of Mg, Fe, Ni, Al, Zn, Mn)Si2O5(OH)4

Jadeite Jade

NaAlSi2O6 (Sodium Aluminum Silicate)

Tumbled dark green stone, likely serpentine or nephrite jade

Serpentine-group minerals, commonly antigorite/lizardite; possibly nephrite (interlocking tremolite-actinolite)

Likely nephrite jade pebble

Nephrite, an interlocking amphibole aggregate dominated by tremolite–actinolite, Ca₂(Mg,Fe)₅Si₈O₂₂(OH)₂

Quartz (specifically Milky or Clear Quartz)

Silicon Dioxide (SiO2)

Green serpentine

Serpentine-group minerals, chiefly lizardite and antigorite; approximate formula Mg₃Si₂O₅(OH)₄

Quartz / Vein Quartz

Quartz (Silicon Dioxide, SiO2)

Quartz Pebble

Silicon Dioxide (SiO2)

White Nephrite Jade

Nephrite (Ca2(Mg, Fe)5Si8O22(OH)2)

Tumbled dark stones, likely basalt and slate

Basalt (fine-grained mafic rock) and slate (foliated metamorphic rock); exact identification is uncertain from the image

Tumbled yellow-green stone, likely serpentine or nephrite jade

Serpentine-group mineral, commonly antigorite/lizardite; possible nephrite, a tremolite–actinolite amphibole aggregate

Tumbled dark-green stone, likely nephrite jade

Nephrite jade, a compact tremolite–actinolite amphibole aggregate (Ca₂(Mg,Fe)₅Si₈O₂₂(OH)₂); identification from the photo is uncertain

Serpentine (Serpentinite)

Serpentinite (Mg, Fe, Ni, Al, Zn, Mn)2-3(Si, Al, Fe)2O5(OH)4

Mixed mineral and rock collection

Predominantly quartz varieties, including amethyst, plus likely calcite, feldspar, mica, and miscellaneous polished stones

Basalt (Vesicular)

Basalt (Extrusive Volcanic Rock)

Nephrite Jade

Ca2(Mg,Fe)5Si8O22(OH)2

Ruby (Pinkish-Red)

Corundum (Al2O3 with Chromium trace)

Quartz

Silicon Dioxide (SiO2)

Tumbled green stone, likely serpentine or nephrite jade

Serpentine-group minerals, commonly antigorite/lizardite; possible nephrite, a jade variety of tremolite–actinolite

Quartz (Milky or Clear Quartz fragment)

Silicon Dioxide (SiO2)

Nephrite Jade

Tremolite-Actinolite series (Ca2(Mg,Fe)5Si8O22(OH)2)

Nephrite Jade

Nephrite (Ca2(Mg, Fe)5Si8O22(OH)2)

Quartz (Milky/Clear Quartz)

Silicon Dioxide (SiO2)

Tumbled dark green stone, likely serpentine or nephrite jade

Serpentine-group minerals, chiefly antigorite/lizardite; possibly nephrite, an aggregate of tremolite–actinolite
