Man Made Material (Jewelry, Metal Alloy)

Diamond (or Simulant)

Carbon (C) or relevant simulant formula (e.g., ZrO2 for Cubic Zirconia)

Opalite is a trade name for opalescent glass, not a natural mineral; composition is typically silica glass with additives

Sea Glass

Man-made vitreous material

Aura Quartz (Titanium/Gold coated)

Silicon Dioxide (SiO2) with metallic vapor deposition

Red gemstone ring, likely garnet or synthetic ruby

Possibly almandine garnet (Fe₃Al₂(SiO₄)₃) or corundum/ruby (Al₂O₃); image alone cannot distinguish

Goldstone (aventurine glass)

Man-made copper-bearing glass; not a natural mineral (commonly sold as blue/brown goldstone)

Opalite

Synthetic Opalised Glass

Diamond-set gold ring

Diamond (crystalline carbon, C) in a gold alloy setting

Sea Glass

Man-made vitreous material

Gem-set gold ring

Unidentified transparent gemstone, possibly quartz or glass, set in a gold-colored metal ring

Opalite

Synthetic Opalite (Man-made glass)

Opalite

Synthetically produced glass (Silicon Dioxide with metallic inclusions)

Man-made Glass (Tumbled/Shaped)

Amorphous Silicon Dioxide (SiO2) with metal oxide colorants

Opalite

Synthetic Fluorescent Glass (SiO2 + impurities)

Cullet Glass / Slag Glass

Amorphous silica glass

Opalite (Man-made Glass)

Fused glass (typically made of dolomite and metal opacifiers)

Opalite

Synthetic Glass (typically Silica/Magnesium based with metal additives)

Vesicular basalt (probable iron-rich volcanic rock)

Basalt; chiefly plagioclase, clinopyroxene, olivine, and Fe-Ti oxides

N/A - Non-Geological Item

Aura Rose Quartz

SiO2 (Silicon Dioxide with Titanium/Gold coating)

Goldstone

Aventurine Glass (Man-made)

Malaysian 50 Sen Coin

Coinage (specific alloy unknown without metallurgical analysis, but typically brass or bronze for this denomination and era)

Rose Quartz and Cherry Quartz (Dyed Glass/Quartz)

Silicon Dioxide (SiO2) with inclusions/dye

Slag Glass

Vitreous Silicate Residue

Opalite

Man-made opalescent glass (SiO2 + metal oxides)

Titanium Aura Quartz (Bismuth-coated Druzy)

Silicon Dioxide (SiO2) with Titanium/Metal vapor coating

Ornamental ring with likely blue sapphire and diamonds

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

Titanium Coated Kyanite (Aura Kyanite)

Aluminosilicate (Al2SiO5) with a Titanium-Niobium vacuum-deposited coating

Diamond-set gold ring

Diamond (carbon, C) in a gold alloy setting; the image does not establish the stone’s identity or authenticity

Synthetic Resin Charm (Seal Shape)

Polymer Resin with plastic glitter / Polyethylene terephthalate glitters

Blue crystal pendant (likely blue glass or synthetic crystal)

Not identifiable from the image; possibly synthetic quartz or glass, rather than a natural mineral

Slag

Anthropogenic glassy silicate

Gold (Elemental Metal)

Gold (Au)

Diamond (in a gold ring)

Diamond (pure carbon, C)

Opalite

Synthetic glass (SiO2 + metal additions)

Opalite (Man-made Glass)

Synthetic Silicon Dioxide Glass (SiO2 + metal oxides)

Opalite-style pendant (likely synthetic glass, not natural opal)

Opalescent glass; commonly sold as “opalite” (not a recognized mineral species)

Native Silver

Silver (Ag)

Blue cabochon ring stone, likely lapis lazuli or blue chalcedony

Uncertain from image; possible lazurite-bearing lapis lazuli (Na₃Ca(Si₃Al₃)O₁₂S) or cryptocrystalline quartz (SiO₂)

Possible obsidian or slag glass

Volcanic glass, primarily SiO₂; alternatively industrial iron-rich glassy slag
