Mineral (Refined Metal)

Beryl in Quartz Matrix

Beryllium Aluminum Silicate (Be3Al2Si6O18)

Milky Quartz

Quartz (Silicon Dioxide, SiO2)

Amber jewelry (possibly amber-colored glass or resin)

Amber — fossilized plant resin, chiefly composed of polymerized terpenoids; the pictured material cannot be confirmed from the image

Amygdaloidal Basalt

Mafic extrusive igneous rock with secondary mineral infills

Opalite

Synthetic glass (Opalite simulant)

Pyrite

Iron Sulfide (FeS2)

Limonite-stained Gossan/Ironstone

Goethite and Hematite (Fe2O3 • nH2O)

Bauxite

Aluminium ore (Hydrated aluminium oxides AlOx(OH)3-2x)

Colorless Quartz (Rhinestone)

Silicon Dioxide (SiO2)

Bauxite

Bauxite (Al2O3·2H2O)

Amber cabochon pendant

Amber (fossilized tree resin; chiefly polymerized terpenoids)

Granite

Granite (Intrusive Igneous Rock)

Quartz Vein / Quartz Matrix

Silicon Dioxide (SiO2)

Yellow Beryl (Heliodor)

Beryllium aluminum silicate (Be3Al2Si6O18)

Opalite-style glass pendant

Man-made opalescent glass (not natural opal)

Pyrite in Quartz

Silicon Dioxide (SiO2) with Iron Sulfide (FeS2)

Small metallic mineral grain, possibly native silver

Unconfirmed; native silver (Ag) is one possibility, but the photograph alone cannot distinguish it reliably from other metallic minerals or metal debris.

Copper Ore with Malachite and Chalcocite

Copper-bearing Mineral Assemblage (Cu2CO3(OH)2 + Cu2S)

Lepidolite

K(Li,Al)3(Al,Si,3O10)(F,OH)2

Beryl (likely var. Aquamarine or Goshenite) in Matrix

Beryllium Aluminum Silicate (Be3Al2Si6O18)

Faceted clear gemstone ring, likely quartz or glass imitation

Unidentified colorless faceted material; quartz (SiO₂) is possible, but the image cannot distinguish it from glass or another gem

Mystic Topaz (Treated Quartz or Topaz)

Aluminum silicate fluoride hydroxide [Al2SiO4(F,OH)2] with thin-film metallic coating

Green Aura Quartz (Titanium treated Kyanite or Quartz)

Silicon Dioxide (SiO2) or Aluminum Silicate (Al2SiO5) with Titanium/Metal Oxide coating

Granite

Felsic intrusive igneous rock

Likely galena (lead sulfide)

Galena, PbS

Native Gold Flake

Gold (Au)

Aura Quartz Geode

Titanium/Gold bonded Quartz (SiO2 with metallic coating)

Orgonite Pyramid with Amethyst and Quartz

Silicon dioxide (Quartz/Amethyst) embedded in resin with metal shavings

Felsic intrusive igneous rock

Serpentine

Serpentine subgroup (Mg,Fe)3Si2O5(OH)4

Native metal specimen, likely galena or metallic slag

Probably galena (lead sulfide, PbS); identification is uncertain from the image alone
