Noreena Jasper occurs in the Pilbara region of Western Australia, not far from the iron ore mining town of Newman, some 700 miles north of the capital, Perth.

The rock tends to break into angular pieces which contain the most wonderful "geometric", abstract designs. Until the rock is cut, you do not know what will be revealed.

Noreena Jasper is from the same geological formation as Munjina Stone. They both occur in the Jeerinah Formation which is part of the Fortescue Group in the Hamersley Basin. Age is late Archaean and was deposited between 2765 and 2687 million years ago

It is a silicified pelite (mudstone).
