Polished White Opal Gemstone For Jewellery

Opal is a captivating and unique gemstone known for its vibrant play of colors and its iridescent beauty. Here's some information about the opal stone:

Color Play: Opal is renowned for its striking play of colors, which can include a wide spectrum of hues, including red, orange, green, blue, violet, and more. This phenomenon is called "opalescence" and is caused by the diffraction of light as it passes through the microstructure of the stone.

Chemical Composition: Opal is composed primarily of hydrated silica (SiO2·nH2O). It is classified as a mineraloid rather than a mineral because it does not have a crystalline structure. Opal's unique play of colors is attributed to the arrangement of its tiny silica spheres.
