Opals have their own optical effect called Opalescence or better known "Play of Colour". It is when they have an optical phenomenon that occurs when light enters an opal, interacts with its internal structure, and leaves the opal in a flash of spectral colours.
The most fought after opals are the ones that display all the rainbow spectrum, especially flashes of red. This opal is a fantastic example of this, flashing blue, green, yellow, orange and reds. Unfortunately, it has not photographed well under the light box so we recommend you request a video from us!}
