Mineral And Metamorphic Rock

Aventurine (likely Green Aventurine)

Silicon Dioxide (SiO2) with mineral inclusions

Milky Quartz

Silicon Dioxide (SiO2)

River Cobble (Phyllite or Quartzite)

Metasedimentary Rock (often containing SiO2 or KAl2(AlSi3O10)(OH)2)

Quartz (Smoky/Rock Crystal)

Silicon Dioxide (SiO2)

Biotite-rich gneiss (probable)

Foliated quartz–feldspar–biotite gneiss; composition commonly includes quartz (SiO₂), feldspar, and biotite mica

Gneiss

Gneiss (a rock type, not a specific mineral with a formula)

Lapis Lazuli

Lazurite-dominant rock, (Na,Ca)8(AlSiO4)6(SO4,S,Cl)2

Mica Schist

Medium-grade regional metamorphic rock (composition varies)

Quartzite Pebble

Metamorphic Quartzite (SiO2)

Schist

Mica Schist (formula variable based on mineral content, typically containing [K,Al,Fe,Mg,Si,O,H])

Slate

Foliated Metamorphic Rock (composed primarily of silica and alumina with iron and magnesium)

Jade

There are two distinct minerals commonly known as Jade: Nephrite (a calcium magnesium silicate - Ca2(Mg,Fe)5Si8O22(OH)2) and Jadeite (a sodium aluminum silicate - NaAlSi2O6). Based on the image showing a typically softer, more fibrous appearance, it is likely Nephrite.
