Opal
Opal is deposited at a relatively low temperature and may
occur in almost any kind of rock, being most commonly found with
limonite, sandstone, rhyolite and basalt. The word opal comes from the
Latin opalus, by Greek opallios.The water content is usually between
three and ten percent, but can be as high as twenty percent. Opal ranges
from clear through white, gray, red, orange, yellow, green, blue,
magenta, rose, pink, slate, olive, brown, and black. Of these hues, the
reds against black are the most rare, whereas white and greens are the
most common. These colour variations are a function of growth size into
the red and infrared wavelengths. Opal is Australia's national gemstone.
Australia produces around 97% of the world's opal. Precious opal shows a
variable interplay of internal colours and even though it is a
mineraloid, it does have an internal structure. At micro scales precious
opal is composed of silica spheres. These ordered silica spheres
produce the internal colours and determines the quality of precious opal.
