Rhinestone (or glass crystal)

Silicon dioxide (if glass) / Various

Turquoise-colored stone chip necklace

Likely turquoise (CuAl₆(PO₄)₄(OH)₈·4H₂O); appearance alone cannot rule out dyed howlite or another imitation.

Turquoise

Hydrated phosphate of copper and aluminium [CuAl6(PO4)4(OH)8·4H2O]

Tumbled aqua glassy mineral specimen, likely chrysocolla or turquoise imitation

Uncertain from image; possible chrysocolla (hydrated copper aluminosilicate, variable composition) or dyed/man-made glass

Pearl

Calcium Carbonate (Aragonite or Calcite) and Conchiolin

Faceted color-change gemstone, likely synthetic alexandrite or glass imitation

Alexandrite: chrysoberyl, BeAl₂O₄; exact identification requires gemological testing

Pink/red faceted gemstone, likely synthetic corundum or glass imitation

Nephrite Jade

Nephrite (Ca2(Mg,Fe)5Si8O22(OH)2)

Strawberry Quartz

Silicon Dioxide (SiO2) with inclusions of Goethite or Hematite

Gemstone ring (stone appears pale yellow, possibly citrine or glass imitation)

Undetermined; possible quartz variety citrine (SiO₂)

Wood Beads (Palmwood/Ebony)

Various species for wood, but often refers to woods like Palmwood (e.g., Borassus flabellifer) or Ebony (Diospyros spp.) for their distinctive grain and hardness.

Rutilated Quartz

SiO2 with TiO2 inclusions (Rutile)

Faceted clear quartz (rock crystal), likely a cut imitation or low-grade gemstone

Quartz, silicon dioxide (SiO₂)

Aquamarine

Aquamarine (Beryl variety); Be3Al2Si6O18

Tiger's Eye

Tiger's Eye (a variety of Chalcedony, which is a microcrystalline quartz with fibrous inclusions of oxidized crocidolite)

Moonstone

Adularia or Orthoclase (KAlSi3O8) or Albite (NaAlSi3O8), specifically with lamellar exsolution of albite and orthoclase.

Amazonite

KAlSi3O8 (Potassium Feldspar, variety of Microcline)

Green Aventurine

Quartz (SiO2) with Fuchsite inclusions

Turquoise

Turquoise (CuAl6(PO4)4(OH)8·4H2O)

Goldstone and pink quartz bead strands

Goldstone is aventurescent copper-bearing glass; pink beads are likely rose quartz (SiO₂), though dyed or glass imitations are possible

Blue Tiger's Eye

Riebeckite (crocidolite variety)

Red Coral

Corallium rubrum (for precious red coral), although other species like Corallium japonicum and Paracorallium are also used.

Moonstone

Orthoclase Feldspar (KAlSi3O8)

Jade

There are two distinct minerals classified as Jade: Jadeite (Na(Al,Fe3+)Si2O6) and Nephrite (Ca2(Mg,Fe)5Si8O22(OH)2). Based on the image showing translucent, somewhat fibrous material, it is likely Nephrite.

Jade (likely Nephrite or Jadeite)
