Quartzite

Metamorphic Quartzite (SiO2)

Green Agate

Silicon dioxide (SiO₂)

Red glassy cabochon, likely synthetic ruby or red glass

Uncertain; possible synthetic corundum (Al₂O₃, chromium-colored) or man-made glass

Tumbled opalite (likely synthetic glass)

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

Note on Image Identification: Textile
