More and more known, it does not present this effect rainbow: it is the own blazing color which is very sought and which was worth this naming: opal of Fire(Light). It can go of the yellow to the brown via the most beautiful some red. It is a member of precious opals.
The Opal was compared with the galaxies and with the fireworks. We gave them magic names such as Pandora or the Light of the World.
There is 60 million years, while dinosaurs lived on the Earth, the Opal built up itself. Indeed, as all the stones, the Opal is a beauty of the nature which put millions of years to form.
