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

Amber

Succinite (Fossilized Tree Resin) - C10H16O

Garden Quartz (Lodalite)

Silicon Dioxide with various mineral inclusions (SiO2)

Opalite

Synthetically produced glass (Silicon Dioxide with metallic inclusions)

Tumbled opalite (likely synthetic glass)

Opalite; typically man-made opalescent soda-lime glass, not a recognized mineral species

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

Smoky Quartz

SiO2 (Silicon Dioxide)

Clear Quartz (Rock Crystal)

Silicon Dioxide (SiO2)

Red cabochon ring, likely ruby or synthetic ruby

Corundum (Al₂O₃), possibly chromium-bearing ruby; the image cannot establish whether it is natural or synthetic

Blue Goldstone

Goldstone (Brown)

Aventurine Glass (Silicon Dioxide infused with Copper crystals)

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

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

Blue gemstone, likely iolite or blue sapphire

Iolite (cordierite, Mg₂Al₄Si₅O₁₈) or corundum (sapphire, Al₂O₃)

Red glass-like crystal, likely synthetic ruby or red glass

Uncertain from image; possible corundum (ruby), Al₂O₃, or synthetic glass

Opal ring

Common opal, likely synthetic or assembled blue-green opal (hydrated amorphous silica, SiO₂·nH₂O)

Opalite

Synthetic Glass (Simulated Opal)

Amber

Succinicum (C10H16O)

Flint / Chert Nodule

Microcrystalline quartz (SiO2)

Quartz (Druzy / Goldstone Gemstone Cabochon)
