Metamorphic Rock (For Both Nephrite And Jadeite)

Green glassy mineral specimen, likely nephrite or serpentine

Serpentine

Serpentinite (Mg,Fe,Ni,Al,Zn)3Si2O5(OH)4

Serpentine (Infinite Stone)

Serpentinite (Hydrous magnesium iron silicate)

Serpentine (New Jade)

Antigorite/Lizardite [Mg3Si2O5(OH)4]

Serpentinite

Serpentinite (composed primarily of Serpentine group minerals: (Mg,Fe)3Si2O5(OH)4)

Jadeite (Jade)

Jadeite (NaAlSi2O6)

Yellow Jade (Quartzite Jade)

Quartzite (SiO2)

Serpentinite

Serpentinite (composed largely of serpentine group minerals including antigorite, lizardite, and chrysotile)

Glaucophane Schist (Blueschist)

Glaucophane Schist

Rounded greenstone pebble

Likely serpentinite or chlorite-rich metamorphic rock; exact identification requires testing

Jadeite (Icy Jade Bangle)

Jadeite, NaAlSi2O6

Polished green stone, possibly serpentine or nephrite jade

Serpentine-group minerals, chiefly Mg₃Si₂O₅(OH)₄; alternatively nephrite, a tremolite–actinolite aggregate

Lavender Jadeite

Jadeite ($NaAlSi_2O_6$)

Green serpentine or nephrite-like stone

Serpentine-group minerals, chiefly antigorite/lizardite; possibly minor chlorite or actinolite

Jadeite Carving (Pixiu)

Jadeite (NaAlSi2O6)

Serpentine

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

Tumbled green stone, likely serpentine

Serpentinite; chiefly serpentine-group minerals (antigorite, lizardite, chrysotile)

Tumbled serpentine

Serpentinite; chiefly antigorite, lizardite, and/or chrysotile Mg₃Si₂O₅(OH)₄

Likely polished greenstone or serpentine inlay

Serpentine-group mineral, commonly antigorite/lizardite; possibly nephrite jade

Serpentine (Serpentinite)

Serpentinite / (Mg,Fe)3Si2O5(OH)4

Quartzite / Sandstone

Quartzite (SiO2-rich metamorphic rock)

Quartz Pebble

Silicon Dioxide (SiO2)

Unakite (Tumbled)

Unakite (altered granite)

Tumbled dark-green stone, possibly serpentine

Undetermined; serpentine-group rock (predominantly serpentine minerals) is a tentative visual identification

Jadeite

Jadeite (NaAlSi2O6)

Jade Bangle (Jadeite)

Jadeite (NaAlSi2O6)

Quartz pebble

Silicon dioxide (SiO2)

Engraved green stone worry pebble

Likely nephrite jade (tremolite–actinolite series); identification is uncertain from the image

Black Tourmaline (Schorl)

Sodium Iron Aluminum Borate Silicate (NaFe3Al6(BO3)3Si6O18(OH)4)

Polished green-and-white stone, likely serpentine or nephrite jade

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

Tumbled serpentine

Serpentinite; chiefly serpentine-group minerals, Mg3Si2O5(OH)4

Serpentinite

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

Quartz River Rock

Silicon Dioxide (SiO2)

Serpentine (variety: Serpentine Rock)

Antigorite, Lizardite, or Chrysotile; formula generally (Mg,Fe,Ni,Al,Zn,Mn)2-3(Si,Al,Fe)2O5(OH)4

Weathered garnet-bearing gneiss

Quartz–feldspar–mica gneiss with almandine garnet, chiefly Fe₃Al₂(SiO₄)₃

Likely green aventurine or serpentine fragment

Quartzite with fuchsite inclusions (aventurine), or serpentine-group mineral; exact identification requires testing

Granitic Quartz / SiO2 with KAlSi3O8

Dyed Pink Quartzite (Jadeite Simulant)

Silicon Dioxide (SiO2) with organic dye

Likely serpentine or serpentinite

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

Tumbled green-yellow stone, likely serpentine or nephrite jade

Serpentine-group mineral aggregate, commonly lizardite/antigorite; possible nephrite (interlocking tremolite-actinolite)

Green serpentine or nephrite jade fragment

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