What Is The History Of Opal?
There may be several opal origins; one is that it comes from a Sanskrit word "upala", meaning precious stone.
The Romans knew it by "opthalmus" being the Greek word for "eye" and also as "opalus".
To the Romans opal was very much valued, used as a preventative medicine against "eye" disease, as well as a universal good luck charm.
In itself Opal has been a precious stone for a very long period of history.
Australia’s National Gemstone Is The Opal .....
The history of opal in Australia began millions of years ago when parts of Australia were covered by a vast inland sea.
Over a period of time, water and rain floods flushed water, containing silica minerals from the ground surface, down into cavities and niches in sedimentary rocks.
Over a long period of time the silica stone transformed itself into Opal with the silica mixture also replacing any organic material including any plants, animals, sea shells, wood & bone deposited there making "opalised fossils".
When the water itself evaporated, any remaining silica formed a gel (minute silica spheres) hardening over time into what we know now as opal.
Opals, put simply, are a gel from silica with varying percentages of water.
The water content of opal varies between three and ten percent with opal having a hardness on the Moh's scale of 5.5 to 6.5.
The opals fantastic colour play is caused by the silica spheres dissecting light on its passage through the gemstone and turning it into all the colours of the rainbow. Where the spheres are larger and less uniform, the range of colour is much less.
Apart from Australia, opal is found in Mexico, Brazil's north, and also in the USA states of Nevada and Idaho as well as in Ethiopia.
In recent times opal has been discovered in Canada as well.
Over 90% of the world's opal supplies are mined in Australia.

Aboriginal Opal Mythology .....
There are also many legends that surround the Australian opal gemstone.
" In the dreamtime of the aborigines, it is said that the Creator came down to Earth on a rainbow to bring the message of peace to humans and at the point where his foot touched the earth, the stones started sparkling and came alive with all the colours of the rainbow.
Thus was the birth of Opals!"
The following is an interesting aboriginal story, extract courtesy of Janes Oceania/Australia - (http://www.janesoceania.com/australia_home/index.htm) .....
"Opals, like other minerals, have a spiritual value in that they represent a part, such as an organ, a Dreaming ancestor left behind as a sign of his or her presence at a particular spot. Certain minerals and stones are imbued with the powerful energy of the ancestor.
The Adnyamathanha elders relate two stories about opals.
The first is about a young boy who was chasing a kangaroo. he caught it at Minipa with his wooden club, then sat down to have a meal. While he ate, he stuck his club in the ground so that it stood up.
The club turned into opal stone.
This story refers to the vertical or oblique planes of rock in which opal is found, one end of which is on or near the surface.
The second story is about Marnbi the bronze-winged pigeon, who threw a firestick high into the air. It landed near Cooper Pidy, an important opal mining area. When it came down and hit the ground sparks flew off in all directions.
These became opals."
