An opal is a hydrated form of silica with a water content ranging from 3 to 21%.Indeed, it is this permeability to water that makes it a hydrophile.
Opals are deposited at a relatively low temperature and may occur in the fissures of almost any kind of rock, being most commonly found with limonite, sandstone, rhyolite, marl, and basalt. Precious opals show a variable interplay of internal colors.

At microscopic scales, precious opal is composed of silica spheres some 150 to 300 nm in diameter in a hexagonal or cubic close-packed lattice. These ordered silica spheres produce the internal colors by causing the interference and diffraction of light passing through the microstructure of the opal.

The opal is very nice with hues of red, but in real light, it is more translucent and dark blue is not so visible. It would be fair to post as well a photo taken with daylight to see everyday reality.

Die Fotos sind nicht entsprechend der Ware. Offensichtlich nachbearbeitet und die Farben verstärkt! Werde nichts mehr bestellen!
