Celebrate October's Birthstone - Natural Colourful Opal with Diamond

Opal gemstones are a captivating and diverse group of precious stones known for their unique play-of-color and stunning visual effects. Formed from silica deposits that have gradually solidified over millions of years, opals display a wide range of colors and patterns, making each stone truly one-of-a-kind. What sets opal apart from other gemstones is its ability to diffract light, creating a mesmerizing display of rainbow-like hues that shift and change as the gemstone is moved. This phenomenon, known as "opalescence," is most pronounced in precious opal, which exhibits vivid color play against a backdrop of body color that can range from translucent to opaque.
