From Ethiopia and Australia including Welo and Coober Pedy, these opals are especially well known for their transparency with brilliant flashes of color.

History and Significance of Opals

Opals have a rich history spanning thousands of years. The name “opal” is said to come from the Sanskrit word “Upala”, which means “precious stone”, and later from the Greek term “Opallios”, which means “to see a change of color”. Opals were highly valued by ancient civilizations such as the Romans, who considered them a symbol of purity and hope.

The history of opal mining dates back to prehistoric times, with evidence of the use of opal found in ancient artifacts. However, it was not until the discovery of large opal deposits in Australia in the late 19th and early 20th centuries that opal gained popularity. Australia is still the largest producer of opal in the world, with about 95% of the world’s opal supply coming from the country.

 Opals are valued not only for their beauty, but also for the mystical properties attributed to them. In the middle Ages, opals were believed to bring good luck and were often associated with eyes because of their iridescent appearance. Some cultures considered the opal a symbol of loyalty and security, while others believed it could ward off evil spirits.

Why Opals Are Valuable

Opals are unique among gemstones because of their ability to refract light, resulting in a fascinating play of colors. This optical phenomenon, known as “color play”, occurs when light passes through spheres of silica in the opal, creating flashes of color on the surface of the stone. The value of the opal is determined by its body color, color scheme and general appearance.

The most valuable opal are those with a dark body (such as black opal), which provide a wonderful contrast to the vivid colors displayed. In addition, the pattern, luster and color distribution in the stone also significantly affect its value. Opal with a bright and uniform play of colors and a pleasing pattern are highly sought after by collectors and jewelry enthusiasts.
