Mica schist; likely composed of quartz and mica (muscovite and/or biotite), with possible feldspar

Tumbled chalcedony (likely agate)

Microcrystalline quartz, SiO₂; chalcedony, possibly banded agate

Faceted clear gemstone ring, likely white sapphire or diamond

Unidentified colorless gemstone; diamond (C) or sapphire (Al₂O₃) cannot be distinguished from the image

Probable serpentinite-rich greenschist; commonly dominated by serpentine-group minerals, chlorite, actinolite, and magnetite

Polished banded stone, likely labradorite or gneiss

Probably feldspar-rich gneiss; possible labradorite-bearing rock (plagioclase feldspar, chiefly (Ca,Na)(Al,Si)₄O₈)

Small polished jasper or agate pebble

Likely microcrystalline quartz (SiO₂); exact variety cannot be determined from the photo

Iron-rich rock fragment (tentative)

Unidentified iron oxide/hydroxide-rich material; possible hematite or goethite

Likely iron-rich breccia or weathered ironstone

Ironstone breccia; composition cannot be confirmed from the photograph

Chromite-bearing serpentinite (probable)

Serpentinite with disseminated chromite; chromite is FeCr₂O₄

Weathered rock fragment, possibly basalt

Unidentified fine-grained mafic rock; basalt is a tentative visual identification

Conglomerate (possibly concrete-like natural breccia)

Lithified, poorly sorted clastic rock with angular to subrounded mineral and rock fragments in a finer matrix

Green aventurine pendant (likely)

Quartz, SiO₂, with green fuchsite inclusions (aventurescent quartz)

Likely gypsum (selenite/alabaster), possibly a weathered evaporite fragment

Gypsum, CaSO₄·2H₂O

Polished serpentine (likely green serpentine)

Serpentine-group minerals, chiefly antigorite, lizardite, or chrysotile; composition varies

Ironstone (limonite/goethite-rich rock)

Limonite, a mixture of hydrated iron oxides, commonly including goethite (α-FeO(OH))

Blue kyanite (probable)

Kyanite, Al₂SiO₅

Polished gemstone beads, likely brown tiger’s eye with an orange bead and a green bead

Tiger’s eye: fibrous quartz (SiO₂) with iron-oxide inclusions; the orange and green beads cannot be identified confidently from the image

Polished chert (likely jasper or iron-rich chert)

Microcrystalline quartz, SiO₂, colored by iron oxides and possibly clay minerals

Mica-rich schist (likely garnet-mica schist)

Mica schist, composed mainly of muscovite and/or biotite; the reddish-brown grains may be garnet, but cannot be confirmed from the image alone

Pumice

Pumice, a highly vesicular volcanic glass composed mainly of rhyolitic to dacitic silicate material

Likely gneiss

Gneiss, composed chiefly of quartz, feldspar, and mica/amphibole

Small gray stone, possibly granite or quartz-rich pebble

Indeterminate; likely a weathered quartz–feldspar rock fragment

Iron-stained quartz-rich rock (possibly ironstone or quartzite)

Quartz-rich silicate rock with iron oxides; exact rock type cannot be confirmed from the image

Faceted yellow gemstone, possibly citrine

Unconfirmed from the image; if citrine, it is iron-colored quartz (SiO₂).
