Metamorphic Rock (For Both Nephrite And Jadeite)

Serpentine

Serpentine Group (primarily Antigorite or Lizardite), Mg3Si2O5(OH)4

Blue gemstone, likely iolite or blue sapphire

Iolite (cordierite, Mg₂Al₄Si₅O₁₈) or corundum (sapphire, Al₂O₃)

Quartz-rich sandstone (possibly quartzite)

Quartz arenite; if recrystallized, quartzite, composed predominantly of SiO₂

Mixed Rock and Mineral Collection

Mixed Assemblage (includes Quartz, Jasper, Feldspar, and Turquoise-colored stones)

Bornite (Peacock Ore)

Bornite (Cu5FeS4)

Greenstone / River Jadeite pebble

Metavolcanic rock / Chlorite or Actinolite-rich schist

Tumbled serpentine (likely)

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

Unakite

Epidotized Granite

Tumbled serpentinite (likely antigorite-rich serpentine)

Serpentinite; chiefly serpentine-group minerals, Mg₃Si₂O₅(OH)₄, with possible magnetite, chromite, or brucite

Quartz Pebble

Silicon Dioxide (SiO2)

Weathered gray pebble, likely quartzite or chert

Quartzite (microcrystalline SiO₂); possibly chert (cryptocrystalline SiO₂)

Nephrite Jade

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

Jadeite (Jade)

Jadeite, NaAlSi₂O₆

Polished green stone, likely serpentine or nephrite jade

Serpentine-group minerals (commonly antigorite/lizardite) or nephrite, a fibrous tremolite–actinolite aggregate

Icy Jadeite (Jade Bangle)

Jadeite, NaAlSi2O6 (Pyroxene group)

Jadeite Bangle

NaAlSi2O6 (Jadeite pyroxene mineral aggregate)

Serpentine (Nephrite-like Serpentine)

Serpentinite (Hydrous magnesium iron phyllosilicate)

Dark rock specimen (possibly slate or shale)

Unidentified fine-grained rock; slate is foliated metamorphosed shale, while shale is sedimentary mudrock

Quartzite Pebble

Metamorphic Quartzite

Carved stone bowl or mortar

Uncertain; likely steatite (soapstone) or fine-grained volcanic stone

Nephrite Jade

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

Likely quartz-rich pebbles

Quartz (SiO₂), possibly milky quartz or quartzite; identification is uncertain from the blurry image

Bornite (Peacock Ore)

Bornite (Cu5FeS4)

Serpentine-rich rock (likely serpentinite)

Serpentinite; chiefly serpentine-group minerals (Mg₃Si₂O₅(OH)₄), commonly with magnetite, talc, or carbonate

Greenstone / Serpentinite

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

Banded Agate (specifically Eye Agate / Chalcedony)

Agate (Cryptocrystalline variety of Quartz, SiO2)

Beach Pebble (Nephrite Jade / Chalcedony)

Ca2(Mg,Fe)5Si8O22(OH)2 / SiO2

Polished greenstone ring/bead

Likely nephrite jade (actinolite–tremolite amphibole aggregate), possibly serpentine or bowenite

Green Aventurine

Quartz variety (SiO2 with inclusions)

Quartz-bearing rock or quartz-rich mineral specimen

Quartz, silicon dioxide (SiO₂); exact host rock is uncertain from the image

Nephrite Jade

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

Serpentine (Serpentinite)

Mg3Si2O5(OH)4

Quartz (Vein Quartz)

Silicon Dioxide (SiO2)

Likely serpentine or serpentine-rich stone

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

Likely limestone or marble fragment

Calcite-rich carbonate rock; CaCO₃

Tumbled greenstone / serpentinite (probable)

Serpentinite, chiefly Mg-rich serpentine minerals (antigorite, lizardite, chrysotile), possibly mixed with chlorite, magnetite, or carbonate

Green jade-like carved pendant or worry stone

Likely nephrite jade (tremolite–actinolite), but the image alone cannot confirm the material

Blue Apatite

Apatite (Calcium Phosphate) - Ca5(PO4)3(F,Cl,OH)

Greenstone, likely nephrite jade

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

Faceted gemstones, likely mixed small sapphires or spinel

Corundum (Al₂O₃) or spinel (MgAl₂O₄); exact identification requires testing

Yellow Jadeite

NaAlSi2O6 (Sodium Aluminum Silicate)

Unakite

Epidotized Granite
