Synthetic (Man Made Glass)

Dyed Dragon Vein Agate

Silicon Dioxide (SiO2) with artificial pigment

Red gemstone ring, possibly synthetic ruby or red glass

Unidentified red stone; ruby is corundum (Al₂O₃), but the image cannot confirm its identity

Red faceted gemstone, likely synthetic ruby or red spinel

Ruby: corundum (Al₂O₃); spinel: MgAl₂O₄; visual identification alone is insufficient

Green Agate

Silicon dioxide (SiO₂)

Red gemstone ring, likely synthetic ruby or red glass; exact stone cannot be confirmed from the image

Ruby (corundum, Al₂O₃) if natural; the setting appears to be silver-tone metal

Red faceted gemstone, likely synthetic ruby or red glass

Ruby: corundum, aluminum oxide (Al₂O₃), chromium-colored; identity cannot be confirmed visually

Blue Quartz / Glass Gemstone Pendant

SiO2 (Silicon Dioxide) or Synthetic Glass

Zirconia (Ceramic) & Ion-X Glass

Zirconium Dioxide (ZrO2) and Ion-strengthened Aluminosilicate Glass

Man-made Carved Stone (Scream Mask/Skull motif)

Tumbled aqua glassy mineral specimen, likely chrysocolla or turquoise imitation

Uncertain from image; possible chrysocolla (hydrated copper aluminosilicate, variable composition) or dyed/man-made glass

Blue faceted gemstone, likely sapphire

Corundum (Al₂O₃), likely blue sapphire; identity cannot be confirmed from the photograph alone

Black onyx or black obsidian bead bracelet

Likely chalcedony (microcrystalline quartz, SiO₂) if onyx; alternatively volcanic glass (obsidian)

Clear quartz crystal sphere

Quartz (silicon dioxide, SiO₂)

Yellow faceted gemstone, likely citrine or yellow beryl

Quartz (SiO₂), if citrine; beryl (Be₃Al₂Si₆O₁₈), if heliodor

Amethyst quartz cluster

Quartz, SiO₂; purple variety amethyst

Milky Quartz

Silicon Dioxide (SiO2)

Chalcanthite (Likely Synthetic/Lab-Grown)

Hydrated copper(II) sulfate (CuSO4·5H2O)

Terracotta (Man-made ceramic brick fragment)

Baked clay / High-iron ceramic (Silicate-based ceramic)

Pink/red faceted gemstone, likely synthetic ruby or pink sapphire

Corundum, aluminum oxide (Al₂O₃); likely lab-grown or treated material

Blue chalcedony cabochon (probable)

Chalcedony, a cryptocrystalline variety of quartz; silicon dioxide, SiO₂

Dyed Quartz Geode

Silicon Dioxide (SiO2) with artificial pigment

Crackle Glass (Simulated Gemstone)

Amorphous Solid (SiO2)

The user-provided image does not contain a rock or mineral specimen

Clear Quartz (faceted) / Diamond Simulant

Silicon Dioxide (SiO2) / Cubic Zirconia (ZrO2)

Ruby (or potential synthetic/imitation)

Corundum (Al2O3)

Ornamental ring with likely blue sapphire and diamonds

Blue corundum (sapphire), Al₂O₃; surrounding stones appear diamond, C, set in gold-colored metal

Red cabochon gemstone ring, likely synthetic ruby or red glass

Possibly corundum (Al₂O₃, chromium-colored); identity cannot be confirmed from the image

Diamond

Natural Diamond (Carbon, C)

Ruby / Red Corundum

Al2O3 (Aluminum Oxide with Chromium trace)

Blue Sapphire (likely costume glass imitation)

Corundum (Al2O3) with iron/titanium impurities

Hematite Beads

Hematite (Fe2O3)

Costume Jewelry Gemstones (Emerald-imitation and semi-precious beads)

BeCuAl6Si6O18 (Beryl structure), frequently simulated by glass or synthetic spinel

Tumbled blue-green stone, possibly aquamarine or chalcedony

Indeterminate from image; possibilities include beryl (Be₃Al₂Si₆O₁₈) or cryptocrystalline quartz (SiO₂)

Strawberry Quartz (Hematoid Quartz)

Silicon Dioxide with Iron Oxide inclusions (SiO2 + Fe2O3)

Blue-violet faceted gemstone, likely amethyst

Quartz (SiO₂), purple variety colored mainly by iron impurities and irradiation

Faceted quartz crystal sphere (likely rock crystal)

Quartz, silicon dioxide (SiO₂)

Quartz (Druzy / Goldstone Gemstone Cabochon)

Silicon Dioxide (SiO2)

Colorless faceted gemstones, likely quartz (rock crystal)

Quartz, silicon dioxide (SiO₂), trigonal crystal system

Colorless faceted gemstone, likely glass or cubic zirconia

Probably cubic zirconia (zirconium dioxide, ZrO₂); diamond cannot be confirmed visually

Blue slag glass / industrial smelter slag

Man-made iron-rich silicate slag; composition variable, commonly Fe–Ca–Mg–Al silicates with glassy phases

Slag Glass (Cullet)

Amorphous Silicon Dioxide (SiO2) with metal oxide colorants

Cat's Eye Moonstone (Simulated/Synthetic or natural Cat's Eye Quartz/Glass)

There is no single scientific name. The appearance suggests either: Moonstone (feldspar group), Cat's Eye Quartz (SiO2), Apatite (Ca5(PO4)3(F,Cl,OH)), or most likely a synthetic material such as Fiber Optic Glass or 'Opalite' (a type of glass).
