Tumbled amber

Fossilized tree resin; commonly succinite (organic resin, not a mineral)

Amber / Copal

Succinite (fossilized resin)

Cut colorless gemstone, likely diamond

Diamond (crystalline carbon, C)

Polished turquoise

Turquoise (hydrated copper–aluminum phosphate; CuAl₆(PO₄)₄(OH)₈·4H₂O), likely with brown limonite matrix

Turquoise ring cabochon

Turquoise, hydrated copper–aluminum phosphate: CuAl₆(PO₄)₄(OH)₈·4H₂O; likely stabilized or treated matrix turquoise

Amethyst bead bracelet

Quartz, SiO₂; purple variety colored mainly by iron-related defects and irradiation

Tumbled green aventurine (probable)

Quartz, SiO₂, with green fuchsite mica inclusions

Strawberry Quartz (or Rose Quartz / Cherry Quartz)

Silicon Dioxide (SiO2) with Lepidocrocite, Hematite, or Goethite inclusions

Green tourmaline crystal (likely elbaite)

Elbaite tourmaline, a complex borosilicate: Na(Li,Al)₃Al₆(BO₃)₃Si₆O₁₈(OH)₄

Carved orange-and-white jasper (likely flower jasper or brecciated jasper)

Microcrystalline quartz, SiO₂, with iron-oxide inclusions

Ruby zoisite (anyolite) beads

Ruby-bearing zoisite; zoisite Ca₂Al₃(SiO₄)₃(OH), with corundum ruby Al₂O₃

Amethyst

Quartz (Silicon Dioxide, SiO2) with iron impurities

Amber

Succinite (Fossilized Tree Resin)

Polished orbicular jasper (likely ocean jasper)

Silicified microcrystalline quartz (SiO₂), with iron-oxide and other mineral inclusions; exact variety cannot be confirmed from the image

Amber

Fossilized plant resin; chiefly polymerized terpenoid hydrocarbons (succinite when Baltic-type)

Jadeite (Ice Jade)

Jadeite (NaAlSi2O6)

Turquoise cabochon

Turquoise; hydrated copper–aluminum phosphate, approximately CuAl6(PO4)4(OH)8·4H2O (composition varies)

Tumbled brown chalcedony or jasper

Microcrystalline quartz (SiO₂), likely iron-stained chalcedony/jasper

Black rectangular gemstone pendant, likely obsidian or black glass imitation

Most plausibly black obsidian (volcanic glass; SiO₂-rich), though the image cannot exclude synthetic glass or black onyx

Faceted colorless gemstone, likely quartz or glass imitation

Most likely quartz (SiO₂), though the strong glare and visible facet pattern could indicate cubic zirconia or lead glass

Faceted colorless gemstone, likely glass or diamond imitation

Unidentified; possibly diamond (carbon, C) or cubic zirconia (zirconium dioxide, ZrO₂)

Colorless faceted gemstone, likely a small diamond or imitation

Undetermined; diamond is carbon (C), but visual appearance alone cannot distinguish it from cubic zirconia or glass

Blue opalite glass cabochon (likely imitation opal)

Man-made opalescent glass; not a natural mineral

Faceted clear gemstone (likely glass imitation or quartz)

Uncertain; appearance is consistent with colorless quartz (SiO₂), but the strong uniform brilliance may indicate cut glass or cubic zirconia

Polished green aventurine (likely serpentine or nephrite imitation)

Aventurine quartz, SiO₂, if genuine; visually also consistent with serpentine, Mg₃Si₂O₅(OH)₄

Red-orange cabochon, likely carnelian or glass imitation

Carnelian: chalcedony (microcrystalline SiO₂), commonly iron-colored

Moonstone cabochon ring

Adularia moonstone, potassium feldspar (orthoclase, KAlSi₃O₈), possibly imitation or another white translucent gemstone

Crystal Quartz Beads (likely Clear Quartz)

Quartz (SiO₂)

Pink faceted gemstone, possibly pink sapphire

Uncertain from the image; possibly corundum (Al₂O₃)

Diamond

Diamond (C - Pure Carbon)

Amber

Fossilized tree resin; primarily an organic polymer of terpenoid compounds (succinite when Baltic-type)

Turquoise cabochon pendant

Turquoise, hydrated copper–aluminum phosphate: CuAl₆(PO₄)₄(OH)₈·4H₂O; likely stabilized or imitation turquoise

Turquoise jewelry beads/earrings

Turquoise, hydrated copper–aluminum phosphate: CuAl₆(PO₄)₄(OH)₈·4H₂O; possibly reconstructed or imitation turquoise
