Sedimentary (Imitation)

Polished leopard jasper (likely ocean jasper)

Silicified microcrystalline quartz/chalcedony; mainly SiO₂ with iron-oxide inclusions

Blue-dyed tumbled stone, likely howlite or magnesite

Likely dyed magnesite (MgCO₃) or howlite (Ca₂B₅SiO₉(OH)₅); identification is uncertain from the image

Amber (likely a small polished amber piece)

Natural fossil resin; amber is an organic mineraloid, not a crystalline mineral. The image alone cannot confirm authenticity.

Howlite

Calcium borosilicate hydroxide (Ca2B5SiO9(OH)5)

Iridescent polished gemstone, likely opal

Common or precious opal (hydrated amorphous silica, SiO₂·nH₂O), possibly synthetic or glass imitation

Tumbled amber

Fossilized plant resin; chiefly polymerized diterpenoid resin (succinite)

Polished brown jasper (brecciated jasper)

Microcrystalline quartz/chalcedony, SiO₂, with iron-oxide and dark mineral inclusions

Yellow-green serpentine (likely)

Serpentine-group phyllosilicate, commonly lizardite or antigorite; approximate formula Mg₃Si₂O₅(OH)₄

Pearl

Nacre (aragonite, CaCO₃, in an organic conchiolin matrix)

Turquenite (Dyed Howlite)

Dyed Ca2B5SiO9(OH)5 (Calcium Borosilicate Hydroxide)

Green faceted gemstone earrings

Undetermined; possibly green glass or synthetic emerald-type material, rather than identifiable natural emerald

Green cabochon ring stone (likely dyed jade, aventurine, or glass imitation)

Undetermined; possible nephrite jade (Ca₂(Mg,Fe)₅Si₈O₂₂(OH)₂), jadeite (NaAlSi₂O₆), or green aventurine quartz

Lavender Jade and Snowy Quartz (Druzy)

NaAlSi2O6 (Jadeite) / SiO2 (Quartz)

Turquoise (possible Howlite imitation)

Hydrated phosphate of copper and aluminium (CuAl6(PO4)4(OH)8·4H2O)

Pearl

Pearl; primarily aragonite (CaCO₃) in nacre

Diamond (or Clear Quartz / Cubic Zirconia)

Carbon (C) or Silicon Dioxide (SiO2) / Cubic Zirconia (ZrO2)

Carved turquoise beads

Turquoise, CuAl₆(PO₄)₄(OH)₈·4H₂O

Red agate-like polished stone (likely dyed chalcedony)

Chalcedony, microcrystalline SiO₂; possibly dyed quartz or glass imitation

Dyed blue howlite (turquoise imitation), possibly dyed magnesite

Howlite: Ca₂B₅SiO₉(OH)₅; the vivid blue color is artificial dye. Exact identification is uncertain from the photograph alone.

Howlite (polished/tumbled)

Howlite — hydrated calcium borosilicate, Ca₂B₅SiO₉(OH)₅

Green cabochon, likely dyed or imitation material

Undetermined; the image is insufficient to identify a mineral species

Red faceted gemstone, likely synthetic ruby

Corundum (Al₂O₃); ruby is red chromium-bearing corundum

Onyx (Black Onyx)

Onyx (Silicon Dioxide, SiO2)

Hematite bead strand

Hematite, α-Fe₂O₃ (iron(III) oxide)

Orbicular jasper (polished/tumbled)

Silica-rich microcrystalline quartz/chalcedony, commonly with iron-oxide or other mineral orbicules; composition varies by locality

Pearl (Imitation or Cultured)

Calcium Carbonate (Aragonite/Calcite) - CaCO3

Turquoise-colored bead on a metal earring

Unidentified blue-green bead; possibly turquoise (CuAl₆(PO₄)₄(OH)₈·4H₂O), but the image cannot confirm its material

Opal ring (likely precious opal)

Hydrated amorphous silica, SiO₂·nH₂O; the pictured stone may be natural opal or a lab-created/imitation opal

White howlite (likely small tumbled pieces)

Howlite, Ca₂B₅SiO₉(OH)₅

Blue quartz-like mineral specimen

Likely quartz (SiO₂), possibly dyed or coated; exact identification requires testing

Chrysocolla and Malachite Beads

Hydrated copper silicates (Chrysocolla) and Copper carbonate hydroxide (Malachite)

Blue opalite glass (likely man-made)

Opalite glass; a silica-based amorphous glass, not natural opal

Red faceted gemstone, possibly ruby

Corundum (Al₂O₃), if ruby; image alone cannot confirm identity or natural origin

Quartz crystal beads

Quartz (silicon dioxide, SiO₂)

Green aventurine bead bracelet

Quartz (SiO₂), commonly green quartzite/aventurine colored by fuchsite mica or other inclusions

Turquoise cabochon jewelry

Turquoise, hydrated copper–aluminum phosphate: CuAl₆(PO₄)₄(OH)₈·4H₂O

Red Coral (Precious Coral)

Corallium rubrum (Calcium Carbonate, CaCO3)

Clear Quartz (Cut/Faceted Gemstone)

Silicon Dioxide (SiO2)

Tumbled amber (likely)

Amber; fossilized plant resin, commonly succinite (organic material rather than a mineral)

Tumbled coral fragment (likely white calcitic coral)

Calcium carbonate, primarily aragonite or calcite (CaCO₃); exact coral genus cannot be determined from the image

Blue gemstone bead bracelet, likely lapis lazuli or dyed stone

Uncertain from image; possible lazurite-bearing lapis lazuli (Na₃Ca(Si₃Al₃)O₁₂S) or dyed quartz/glass imitation

Blue-dyed howlite (likely)

Howlite, Ca₂B₅SiO₉(OH)₅; dyed blue, often sold as imitation turquoise
