The Phenomenal GemstoneOuterspace-Phenomenon-Opal

Durch Beugung des Lichtes an den gitterartigen Kugelpackungen, aus denen der Opal aufgebaut ist, entsteht sein auserlesenes, buntgeflecktes Flammenspiel. Die Ercheinung ist vergleichbar mit dem farbigen Bild einer Straßenlampe, die man durch das Gewebe eines aufgespannten Regenschirmes betrachtet.

wilhelm schmidt minervaWir bieten Ihnen breite Information aus der Opalenwelt und des Opal-Schmucks.

Opal ist eine amorphe Form von Kieselsäure im Zusammenhang mit Quarz, eine mineraloid Form, nicht ein Mineral. 3% bis 21% des Gesamtgewichtes ist Wasser, aber der Gehalt liegt üblicherweise zwischen 6% bis 10%.

Es wird bei einer relativ niedrigen Temperatur abgeschieden und kann in den Spalten von fast jeder Art von Gestein auftreten und wird am häufigsten mit Limonit, Sandstein, Rhyolith, Mergel und Basalt gefunden. Opal ist der nationale Edelstein von Australien, das umgefehr 80% des weltweiten Bedarfs produziert. Dies umfasst die Produktion des Staates South Australia, rund ein drittel des weltweiten Angebots. Der Schwarzopal aus Lightning Ridge NSW ist der seltenste und der wertvollste Opal.

From Ancient times through to the Middle Ages Opals were sacred. Opals became the quintessential Art Nouveau gemstone, providing the foundation for the first mass production of jewellery at the dawn of the twentieth century.

Opal Mining Terms

"Anyone who possesses this knowledge has a much greater chance of finding Opal.  It would not be necessary to come upon it by chance. If one found sandstone then levels would be looked for, then rising levels, then slides and the greatest thing of all two slides crossing at an angle. A slide could be up to 100 meters long and the run of opal could be in straight line along this to a width of up to 15 meters, but usually much less." - Dr. Archie Kalokerinos

Good Morning,
I have just found your wonderful website.
I produce a monthly e-newsletter which is circulated to the Tourism businesses in Coober Pedy and neighbouring stations plus the Info Centres around SA & the NT.
I wondered if I could use some of your Opal info in my October Edition (Opal Month), mainly the parts in your “About Opal” section – names, spiritual info etc.
I would obviously reference it to your website noting the address so others could read your site.

I am wanting to use your site in an assignment as it is a superb example
of a site to use for a primary teaching unit on gemstones.
Many thanks,
