Introduction to Opal
Opal is a hydrated amorphous silica form mainly found in Australia. It is composed of tiny silica spheres arranged in a regular pattern, which diffracts light to display a spectrum of colors. The history of opal in Australia dates back thousands of years, with evidence of its use by Indigenous Australians for both ornamental and spiritual purposes.
Types of Opal
Opal comes in various types, each distinguished by its color play and formation. The most notable types include Black Opal, renowned for its dark body tone and vibrant flashes of color; White Opal, characterized by its light background with vivid hues; Boulder Opal, formed within ironstone boulders, displaying a mix of colors against its host rock; and Crystal Opal, prized for its transparent or semi-transparent body with intense color play.
Characteristics of Opal
The mesmerizing color play exhibited by opals, known as opalescence, is a result of light interacting with the silica spheres within the gemstone. Opal forms in voids or fissures within sedimentary rocks, such as sandstone or clay, through a process of deposition from silica-rich water.
