Rounded quartz-rich pebble

Likely microcrystalline quartz (chalcedony), possibly weathered quartzite

Tumbled cream-colored stone, likely quartzite or limestone

Probably quartzite (microcrystalline SiO₂); limestone alternative: calcite (CaCO₃)

Weathered greenstone (likely serpentinite or altered basalt)

Serpentinite, primarily Mg-rich serpentine minerals; possibly chlorite/actinolite-bearing altered mafic rock

Carved Mottled Greenish-Yellow Crystal/Glass Object

Unknown; possibly a form of quartz (chalcedony/jadeite/nephrite) or glass/resin.

Unakite

Epidotized Granite
