Physical properties

Hardness: 6-7 Mohs; Color: Varied (brown, pink, green, white, blue); Luster: Vitreous to waxy; Structure: Hexagonal (trigonal) or Amorphous; Cleavage: None (conchoidal fracture).

Formation & geological history

Most are quartz-variety minerals formed from hydrothermal activity or cooling of silica-rich fluids in cavities. Most varieties in this mix (like agates and jaspers) are from the Cenozoic era or younger.

Uses & applications

Commonly used for lapidary work, jewelry making (beads/pendants), home decor, metaphysical practices, and beginner geology education.

Geological facts

Tumbled stones are created in industrial rock tumblers over several weeks using progressively finer silicon carbide grits to mimic natural river erosion at an accelerated pace.

Field identification & locations

Identification includes checking for chatoyancy in the Tiger's Eye, moss-like inclusions in the dark green agate, and the characteristic spots of the Dalmatian Jasper. These are found globally, with major deposits in Brazil, South Africa, and India.
