Factors influencing opal color

Opal color is influenced by various factors. The presence of various chemicals in the stone, such as iron and manganese oxides, can create different gemstone colors due to light diffraction. Other factors that influence opal colors include the angle of observation, the quality of light entering the stone, and the structure of internal voids in the stone.

Factor Description
Chemical Composition The presence of different minerals and elements in opal affects its color.
Angle of Observation The angle from which one views an opal determines the colors seen. At different angles, the color changes intensity or appears to disappear.
Quality Of Light Entering Stone The quality of light entering an opal affects how much light is dispersed within it. Therefore, it influences how bright and vivid or subdued and mellow a color may appear.
Internal Voids Structure The size and arrangement of internal voids also affect colors visible inside an opal.

In addition to these factors are other external ones influencing exposure to harsh weather conditions during processing, handling during transit affects their composition, leading to color change risk post-production. Consequently, storing them away from excessive heat or cold ensures they protect their stunning patterns.

The opal mining industry plays a vital role in determining when deposits could offer new varieties based on their opal formation time thousands of feet beneath Earth’s surface. Caring for them because they are delicate makes sure they last long while maintaining their value.

An interesting story is about the Australian Lightning Ridge opal field, where highly prized black opals are produced. Lightning struck a tree and set adjacent rocks on fire, resulting in a subsequent discovery of “fire opals”; thus named due to the fiery color play displayed in them.
