Appearance and Characteristics of Opal:

The opal is said to be over 60 million years old but this is questionable. More recent analysis seems to indicate that opal can develop in a relatively short period of time but whatever is the case, Australian opals are sought after because of their reputation of being secure with dynamic flashes of color set against a dark background. Hence the term ‘black’ or ‘dark’ opal.  Until black opal was discovered in Australia, the world had only seen white or light colored opal.

Opalescence

One of the unique characteristics of the stone is its opalescence. It has a rainbow-like iridescence that changes according to the angle of observation. The stone possesses the ability to reflect and refract particular wavelengths of light. This play of color really makes opal jewelry come alive!  There are some beautiful gemstones in the world but this stone has the unique characteristic of being able to change colors as it is moved. You could say (as did the ancient historian Pliny) that opal is a combination of many gemstones. “The red of the ruby, the green of the emerald, the blue of the sapphire, the purple of the amethyst, all glittering together in union indescribable” – Pliny
