Identify any rockfrom a photo.

Chrysocolla-bearing copper ore

Chrysocolla (hydrated copper aluminum silicate, approximately (Cu,Al)₂H₂Si₂O₅(OH)₄·nH₂O), likely mixed with malachite, quartz, and limonite

Dark green-black metamorphic rock, likely serpentinite

Serpentinite; chiefly serpentine-group minerals, commonly antigorite, lizardite, or chrysotile, with magnetite and minor chromite

Pink-and-white quartz-rich rock, likely rose quartz in matrix

Quartz (SiO₂), possibly rose quartz hosted in quartzite or feldspathic rock

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

Amber cabochon or polished amber-like material

Amber (fossilized plant resin), chiefly C10H16O; possibly resin imitation

Milky quartz (rough crystal fragment)

Quartz, silicon dioxide (SiO₂)

Milky quartz fragment

Quartz (silicon dioxide, SiO₂)

Amber-like resin specimen

Likely amber (fossilized tree resin), composition dominated by polymerized diterpenoid resins; exact identification is uncertain from the photograph

Iron-rich chert or weathered jasper pebble

Microcrystalline quartz (SiO₂), likely ferruginous chert/jasper

Tumbled jasper or chert pebble

Microcrystalline quartz (SiO₂), likely iron-stained jasper/chert

Rounded quartz-rich pebble, likely sandstone or granitic-derived pebble

Indeterminate clastic rock; likely quartz-rich sandstone/conglomerate clast

Polished agate (likely fortification or plume agate)

Microcrystalline quartz/chalcedony, SiO₂, with iron-oxide inclusions
