AI-assisted summary
Description from the seller
A fantastic and rare Natural Australian Rough Opal Chips Jar with about 60 -65 cts of opal inside.
The weight indicated includes the container and the opals.
Opals are small chips perfect for inlay and mosaic art.
Please note that the photos were taken on wet opal. Obviously, the wet opal is brighter and more colorful, highlighting the effect that can be achieved after polishing. In Australian mining practice, rough opal is conventionally photographed wet to represent the potential of the stone. For this reason, we encourage you to carefully evaluate the photographs before bidding. Thank you for your attention and happy bidding!
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 relatively low temperatures and can occur in the fissures of almost any type of rock, most commonly found with limonite, sandstone, rhyolite, marl, and basalt. Only precious opals display 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.
