HELLO THERE, I FOUND SOME THING INTERESTING ABOUT OPALS, ALSO APPRECIATE THE BEAUTIFUL PICS THAT TAKEN BY TINO...GREAT JOB..
Opal
can defined as: "An amorphous non-crystalline gem mineral solidified
from gelatinous or liquid silica deposited in cracks and cavities left
by decaying vegetation, wood, crustaceans and bones.
The word opal is adapted from the Roman term "opalus", which means precious stone, but the origin of this word is a matter of debate.
Precious opal is defined as opaline silica with a play of colour. The term, play of colour was created solely to describe opal's beautiful shifting of spectral hues.
Over 95% of the world's precious opal comes from Australia, and opal is Australia's national gemstone.
