Organic (If Resin) Or Synthetic (If Glass); Simulating Sedimentary Or Metamorphic (For Natural Stones)

Red faceted gemstone jewelry setting

Likely synthetic ruby or red spinel centerpiece with colorless accent stones; exact identification requires gemological testing

Small blue cut gemstone, possibly synthetic spinel or glass; species cannot be determined from the photo

Undetermined; blue synthetic spinel (MgAl₂O₄) is one possibility

Tumbled Black Stone

Unknown (possibly basalt, obsidian, or black jasper)

Blue-green faceted pendant stone

Undetermined; possibly synthetic glass or a blue-green gemstone such as topaz or quartz

Dyed or synthetic turquoise-blue glass-like specimen

Likely man-made colored glass or resin; exact identification requires testing

Blue glassy mineral fragment, possibly dyed/cobalt-colored calcite or aragonite

Uncertain from image; vivid blue coloration may indicate treated calcite (CaCO₃), aragonite (CaCO₃), or synthetic glass

Green faceted gemstone earrings, likely synthetic emerald-colored glass or cubic zirconia

Undetermined; possible glass (amorphous silicate) or synthetic cubic zirconia (ZrO₂)

Faceted red gemstone, likely ruby

Corundum (Al₂O₃), red variety colored mainly by chromium

Opal cabochon or opal-like decorative specimen

Hydrated amorphous silica, SiO₂·nH₂O; likely synthetic or assembled opal material

Small colored gemstone or glass cabochons (uncertain)

Not identifiable from the image; the pieces may be colored glass or synthetic stones rather than natural minerals.

Pink faceted gemstone, likely synthetic ruby or pink sapphire

Corundum (Al₂O₃), possibly chromium-colored ruby; synthetic origin likely

Tumbled yellow-brown quartzite or jasper

Quartzite, predominantly microcrystalline quartz (SiO₂), possibly iron-stained jasper

Red faceted gemstone, possibly synthetic ruby or red glass

Unidentified red gem; ruby is corundum (Al₂O₃), while glass is amorphous silicate

Amber

Succinite (specifically for Baltic amber; general formula C10H16O)

Amber-set ring

Amber (fossilized plant resin; organic mineraloid), set in a metal ring

Tumbled Mixed Gemstones and Rocks

Various mineral species including quartz (SiO2) and silicate minerals

Blue Sapphire (Synthetic or Man-made Glass Imitation)

Corundum (Al2O3) if natural; Lead-glass or Spinal if synthetic

Amber

Succinate (Organic Fossilized Resin)

Amber

Succinite (fossilized tree resin)

Blue resin-coated or dyed stone cabochon

Likely dyed chalcedony/agate (microcrystalline quartz, SiO₂); exact material is uncertain from the image

Pink corundum (likely synthetic or treated sapphire)

Corundum, Al₂O₃; pink coloration commonly from chromium or treatment

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).

Colorless faceted gemstone, likely cubic zirconia

Synthetic cubic zirconia (zirconium dioxide, ZrO₂); identity is visual and not definitive

Opalite

Man-made opalescent glass (SiO2 + metal oxides)

Orange cabochon gemstone, likely amber or amber-like resin

Natural amber: fossilized plant resin (organic mineraloid), commonly succinite; exact identification requires testing

Red gemstone ring; likely synthetic ruby or red glass

Undetermined from the image; ruby is corundum (Al₂O₃), while red glass is amorphous silicate

Red gemstone, likely ruby

Corundum (Al₂O₃), colored red by chromium; identity cannot be confirmed from the photo

Green gemstone ring, likely emerald simulant or jade

Uncertain; possible beryl (emerald, Be₃Al₂Si₆O₁₈) or jadeite (NaAlSi₂O₆), but the blurred image may show synthetic glass or another treated stone

Oak-grain Laminate (Industrial/Decorative Furniture Finish)

Melamine Resin-impregnated Decorative Paper on Particleboard (Cellulose/Thermosetting Plastic)

Emerald

Beryl (Be3Al2(SiO3)6) colored by Chromium and/or Vanadium

Black faceted gemstone, possibly black spinel or onyx

Undetermined; candidates include spinel (MgAl₂O₄) or chalcedony (SiO₂)

Chakra Stone (Composite / Man-made Bonded Gemstones)

Composite of Quartz, Lapis Lazuli, Aventurine, Tiger's Eye, and Jasper (SiO2, (Na,Ca)8(AlSiO4)6(S,Cl,SO4,OH)2, etc.)

Pink faceted gemstone, possibly pink sapphire

Uncertain from the image; possibly corundum (Al₂O₃)

Amber (likely a small rough amber piece)

Fossilized plant resin; amber is an organic mineraloid, not a crystalline mineral

Blue cabochon gemstone, likely synthetic glass or dyed stone

Indeterminate from image; possible glass, synthetic spinel, sodalite, or lapis lazuli

Red cabochon gemstone ring (likely ruby or red spinel; identity unconfirmed)

Possibly corundum (ruby, Al₂O₃) or spinel (MgAl₂O₄); visual identification alone cannot distinguish these from glass or synthetic stones.

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

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

Blue Sapphire

Corundum (Al2O3)

Blue sapphire ring

Corundum (aluminum oxide, Al₂O₃), likely heat-treated sapphire

Blue cabochon gemstone ring

Uncertain; likely blue sapphire (corundum, Al₂O₃), blue topaz, or synthetic glass/spinel

Opalite

Synthetic Opalized Glass

Red cut gemstone, likely synthetic ruby

Corundum (Al₂O₃); possibly lab-grown ruby or red glass imitation
