Formation & geological history

Composed of diverse geological materials formed through igneous, sedimentary, and metamorphic processes, collected and mechanical tumbled or polished to round edges and smooth surfaces.

Uses & applications

Popular for rock tumbling hobbies, educational starter collections, wire wrapping, lapidary arts, metaphysical practices, and decorative display.

Geological facts

Assorted rock mixes often contain specimens from all over the world. Common inclusions are quartz varieties like rose quartz and amethyst, cryptocrystalline quartz like jasper and agate, and various silicates like amazonite and feldspar.

Field identification & locations

Identify individual stones by checking hardness (scratch testing), color, transparency, streak, and presence of banding or inclusions. Found globally in alluvial deposits, pegmatites, and mines.
