Australian opal is a unique and highly sought-after gemstone that is mined exclusively in Australia. It is known for its vibrant play of colors, which is caused by the diffraction of light as it passes through the microscopic silica spheres that make up the stone.
Opal can come in a variety of colors, including white, black, and boulder opal, which is a combination of both. However, Australian opal is particularly prized for its intense hues of red, blue, green, and yellow.
The mining of Australian opal is a complex and dangerous process that requires skilled miners and specialized equipment. It is found in remote locations and can only be extracted from underground mines.
