Goldstone (aventurine glass)

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

Cherry Quartz with Rose Quartz

Crystalline Quartz (SiO2) with glass-based synthetic components

Slag (Anthropogenic Glass/Iron byproduct)

Uncertain; likely microcrystalline or crystalline SiO₂ (quartz), potentially with iron-oxide staining

Granite with Cupules / Bedrock Mortars

Granite (felsic intrusive plutonic rock)

Brick

Fired clay or Ceramic material (no specific mineralogical scientific name as it's a composite)

Blue-green cabochon, likely chalcedony or treated glass imitation

Cryptocrystalline quartz (chalcedony/possibly chrysoprase); identification uncertain from image

Likely clear quartz pebble or glassy quartz fragment

Quartz (silicon dioxide, SiO₂)

Strawberry Quartz

Silicon Dioxide (SiO2) with Hematite or Goethite inclusions
