Nothing taken from the Earth gains in value so much for doing so little to it as a gemstone.
Also known as 'GRAPESTONE' See Pictures Below
is the registered tradename for the gem variety of prehnite which
outcrops in many areas of the Antrim Plateau. The name SunJade®
was coined by Gerald Pauley after a member of the prospecting
team during the 19780's, upon breaking open a basalt nodule containg
yellow prehnite exclaimed " Oh, it looks just like bottled
Oh, it looks just like bottled sunlight."
Our prehnite mine, at Wave Hill Northern Territory, Australia, produces the world's best gem grade prehnite and is the only known source of yellow prehnite in the world.
Prehnite is becoming very popular in China and the western world and in recent years the vaaalue of the material has increased making prehnite a collector's gem.
In 2010 we attended the Shenzhen Jewellery Show and sold all the high quality cabochons which led to a growing demand for the cut stones in China. The demand for rough prehnite also also increased as opportunistic gem factories in China and other parts of Asia, compete for the best quality gem grade rough.
We sell our prehnite by the parcel or by the bulka bag, which contains about 1.5 tonnes of uncleaned prehnite.
Prices on graded rough range from $30.00/Kg for specimen and tumbling material to $5,000.00/Kg for the best grade yellow.
Due to the naature of prehnite, we do not sell samples or individual pieces. Our minimum sample parcel is 20 Kgs and price varies according to quality.
