Iridescent opal

The opal takes its name from the Latin “opalus” originally used by Pliny the Elder (23-29 AD) and synonymous with precious stone for the Romans, but the origin of the word comes from the Sanskrit “upala”. .
The success of opal has been affirmed from Antiquity to the present day, the most famous historical opal is the “Trojan fire” fire opal offered by Napoleon 1st (1769-1821) to the Empress Josephine (1763-1814).
The particularity of opal is its iridescence, that is to say iridescent reflections reminiscent of the rainbow, which change according to the angle of vision.
An opal is a mineral composed of hydrous silicon dioxide or silica gel.
Opal always contains a little water from 3% to 13%, but can reach 34% depending on the variety.
Over time, the opal dehydrates, cracks then appear and reduce the iridescence, these cracks normally disappear once the opal is bathed in water.
