Polished dark green stone, likely serpentinite or chlorite schist

Serpentinite (Mg-rich serpentine minerals, commonly antigorite/lizardite) or chlorite-rich schist

Jade Ring

Nephrite (Ca2(Mg,Fe)5Si8O22(OH)2) or Jadeite (NaAlSi2O6)

Tumbled greenstone, likely serpentine

Serpentinite/serpentine-group minerals, chiefly Mg₃Si₂O₅(OH)₄; possibly chlorite-bearing greenstone

Serpentinite

Serpentinite (Mg, Fe, Ni, Al, Zn, Mn)2-3(Si, Al, Fe)2O5(OH)4

Jade bangle

Likely nephrite jade (actinolite–tremolite amphibole); possibly jadeite

Green Jade (Tumbled)

Most consistent with serpentine-group minerals (often antigorite/lizardite); possibly quartz-rich green aventurine

White jade bangle with gray accent bead

Likely nephrite jade (microcrystalline tremolite–actinolite); possibly white jadeite, identification requires testing

Jade bangle

Likely nephrite jade (fibrous amphibole, Ca₂(Mg,Fe)₅Si₈O₂₂(OH)₂); possibly jadeite (NaAlSi₂O₆)
