Aquamarine (Beryl variety) - Be3Al2(Si6O18)

Clear Quartz crystals on a Matrix base (Geode fragment)

Silicon Dioxide (SiO2)

Granite

Granite (a plutonic igneous rock composed of quartz, feldspar, and mica)

River Rock

Sedimentary Rock (various compositions)

Serpentinite (Serpentine Rock)

Serpentinite is a rock composed of one or more serpentine group minerals, chiefly antigorite, chrysotile, and lizardite, with the general formula (Mg,Fe)3Si2O5(OH)4. Often includes other minerals like magnetite, talc, and chromite.

Seraphinite

Clinochlore (Mg,Fe)5Al(AlSi3O10)(OH)8 - specific variety for Seraphinite due to its fibrous inclusions and chatoyancy.

Corundum

Corundum (Al2O3)

Quartzite

Quartzite (primarily composed of SiO O₂)

Serpentine

Serpentine group minerals (e.g., Antigorite, Chrysotile, Lizardite). Chemical formula: (Mg, Fe)₃Si₂O₅(OH)₄

Moss Agate

Moss Agate (a variety of Chalcedony, SiO ₂)

Strawberry Quartz

Quartz (SiO₂) with Goethite (α-FeO(OH)) and/or Lepidocrocite (γ-FeO(OH)) inclusions

Chert (often called Flint or Jasper based on color)

Microcrystalline or Cryptocrystalline Quartz (SiO2)

Basalt

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.
