Noreena Jasper


Noreena Jasper is a semi precious stone material that comes from Pilbara region of Western Australia, some 700 miles north of the capital, Perth.

Noreena Jasper was named after Noreena Station which is the name of the property on which the rock was found and is mined.  This material is mined solely by Glenn Archer of Outback Mining.

Noreena Jasper is a silicified pelite (mudstone) and is believed late Archaean or 2765-2687 million years old. 

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.  The rock forms in geometric shapes with a red rind, but chipping a corner shows the lovely colors and patterns inside. 

The stone has lovely displays of grays, reds, yellows, and oranges.  Often the bright colors look like flames!  Unfortunately the material does usually have natural fracture lines.

Jasper is from the chalcedony/quartz group. It is a microcrystalline variety of quartz that contains up to 20% foreign material. These materials are what determine the color and appearance of the stone. Also because of the foreign materials, jasper is rarely uniform in color, it is usually multicolored, striped, and/or spotted.
