While called “jasper,” it is technically a silicified mudstone, not a pure jasper formed only from quartz replacement — but because it’s cryptocrystalline SiO₂ with iron-based coloring, it’s classified and marketed as a jasper.

Noreena Jasper is widely used in cabochons, beads, and artistic carvings. Because it is only mined in one locality, it carries a kind of exclusivity within the gem trade, much like Mookaite.

Like Mookaite and Boulder Opal, Noreena Jasper has become one of the iconic stones tied specifically to Australia’s geology, reinforcing the country’s identity as a source of unique gem materials.
