Man Made Glass Mineral Simulant

Dyed Pink Quartzite (Jadeite Simulant)

Silicon Dioxide (SiO2) with organic dye

Sandstone (Quartz Arenite)

Sandstone (dominated by SiO2 quartz grains)

Howlite

Howlite (Calcium borosilicate hydroxide, Ca2B5SiO9(OH)5)

Serpentinite

Serpentinite (composed primarily of Serpentine minerals: Mg3Si2O5(OH)4)

Decorative gemstone bracelet or jewelry

Unidentifiable from the blurred image; likely colored glass or synthetic stones, possibly mixed gemstone beads

Smoky Quartz

Silicon Dioxide (SiO2) with trace aluminum and irradiation

Green Slag Glass

Cullet (Amorphous Silicon Dioxide with impurities)

Strawberry Quartz (or Pink Aventurine)

Quartz with Hematite/Goethite inclusions (SiO2)

Sandstone

Arenite (mostly SiO2)

Goldstone (Synthetic Aventurescence Glass)

Cuprous Aventurescent Glass (Silicon Dioxide with Copper inclusions)

Jade

Jade can refer to two distinct minerals: Nephrite (a variety of the mineral actinolite, Ca2(Mg,Fe)5Si8O22(OH)2) and Jadeite (Na(Al,Fe3+)Si2O6). Based on the image, showing a relatively uniform green color and possibly slight translucence in bead form, it is very likely one of these, but determining which one from a photo is difficult without specific testing.
