Unidentified Rock Fragment

Unknown

Unknown Rock Fragment

Undetermined

Dyed red crystal aggregate, likely quartz or salt

Uncertain; possibly dyed quartz (SiO₂) or halite (NaCl)

Small rounded pebble, possibly quartz-rich stone

Indeterminate from image; likely quartz-bearing silicate rock

Unidentifiable blurred specimen

Cannot be determined from the image

Unidentified dark mineral/rock fragment

Indeterminate; appearance may fit a sulfide-bearing rock or iron-rich mineral

Unknown Tumbled Stone

Unknown (Too Blurry)

Likely small iron-rich concretion or weathered mineral fragment

Indeterminate; possibly limonite/goethite-bearing material with quartz or feldspar

Unidentified small rounded mineral/rock fragment

Indeterminate from image; possibly quartz or chalcedony with iron-oxide staining

Unidentified pale mineral or rock specimen

Indeterminate; image quality prevents reliable mineral identification

Unidentified green-gray mineral/rock fragment

Indeterminate from image; possible serpentine-bearing rock or chrysocolla/azurite-bearing material

Unidentified gray rock fragment

Indeterminate from image; possibly quartz- or feldspar-rich silicate material

Likely weathered quartz-rich rock fragment

Indeterminate; possibly quartz-bearing sandstone or chert with iron-oxide staining

Unidentified polished stone fragments

Indeterminate; likely mixed lapidary specimens, possibly jasper, agate, or quartz-bearing rock

Polished amber-colored stone, possibly chert or jasper

Uncertain from image; likely microcrystalline quartz (SiO₂) if chert/jasper

Unidentified dark mineral or rock specimen

Indeterminate from the severely blurred image; possible dark igneous rock or opaque mineral

Indeterminate metallic mineral fragments

Possibly pyrite, chalcopyrite, or metallic sulfide-bearing rock

Likely weathered quartz-bearing rock fragment

Indeterminate; appears to contain quartz (SiO₂) with iron-oxide staining, possibly from quartzite, granite, or pegmatite

Halite (Rock Salt)

Halite (NaCl)

Himalayan Pink Salt (Halite)

Halite (Sodium Chloride, NaCl)

Pink halite (rock salt)

Halite — sodium chloride (NaCl), likely colored by impurities or inclusions

Small dark metallic-looking rock fragment

Undetermined; possibly iron oxide-rich material or a metallic mineral

Mixed mineral and rock collection

Predominantly quartz varieties, including amethyst, plus likely calcite, feldspar, mica, and miscellaneous polished stones

Undetermined Due to Blur (Possible Flesh-Tone Mineral)

Unknown (Insufficient Visual Clarity)

Halite

Halite (NaCl)

Rock Salt (Halite)

Halite (Sodium Chloride, NaCl)

Possible fossil tooth or bone fragment

Indeterminate fossilized vertebrate material; species cannot be identified reliably from this image

Unidentified rounded mineral/rock fragment

Indeterminate; likely a weathered quartz-rich stone or iron-stained granite fragment

Unidentified brown mineral/rock fragment

Indeterminate from image; possibly iron-stained quartz, feldspar, or weathered limonite
