Tumbled turquoise-like stone

Likely turquoise, hydrated copper aluminum phosphate: CuAl₆(PO₄)₄(OH)₈·4H₂O

Dalmatian jasper

Orbicular rhyolite, commonly sold as Dalmatian jasper; quartz- and feldspar-rich volcanic rock with dark amphibole/biotite inclusions

Tumbled blue-green stone, possibly aquamarine or chalcedony

Indeterminate from image; possibilities include beryl (Be₃Al₂Si₆O₁₈) or cryptocrystalline quartz (SiO₂)

Faceted glass-like gemstone (likely synthetic quartz or cubic zirconia)

Identification uncertain; possibilities include synthetic quartz (SiO₂) or cubic zirconia (ZrO₂)

Turquoise-colored ring stone (possibly turquoise or imitation)

Turquoise, CuAl₆(PO₄)₄(OH)₈·4H₂O; identity cannot be confirmed from the image

Tumbled dalmatian jasper (likely)

Microcrystalline quartz/chalcedony with black amphibole or aegirine inclusions; commonly sold as “dalmatian jasper”

Blue-and-white opalite sphere

Opalite (commercial synthetic or glass-based imitation; not true opal), typically silica glass or synthetic opalescent material

Goldstone (with Tiger's Eye and Quartz)

Aventurine glass (Synthetic SiO2 with Cu inclusions)

Decorative opal-like turtle mosaic

Likely imitation or assembled opal material; exact stones cannot be confirmed visually

Gemstone Ring

Various (Likely Glass, Cubic Zirconia, or assorted semi-precious stones)
