Chrysoprase is a variety of chalcedony that is coloured green by the presence of nickel mineralisation. It is sometimes referred to as Australian Jade due to its resemblance to Burmese imperial jade . The majority of
chrysoprase mined
in Western Australia came from a place called Yerilla which is about 100
miles Yerilla is situated in a
belt of country some hundreds of miles in extent that in
places is extremely rich in nickel, Weathering and alteration
(oxidation) of silicate minerals such as serpentine during lateritisation
generates iron oxides The opaline silica can take various forms such as multi-colored dendritic opalite, moss agate (dendritic chalcedony) and of course chrysoprase. The
chrysoprase occurs usually as veins but sometimes nodules in the
saprolitic clays overlying serpentinites and peridotites. There are also many other
locations where chrysoprase has been found, such as Jamieson and
Wingellina which are situated way out in the desert country. Another location, is a
place called Murramunda (an aboriginal name) in the Pilbara
region of Western Australia, not far from the iron ore mining town of
Newman.
