Opal is a unique gemstone renowned for its play-of-color, an optical phenomenon where flashes of vibrant colors, such as red, green, blue, and yellow, shift across its surface when viewed from different angles. This effect is caused by the unique internal structure of Opal, which diffracts light into its spectral components. Opals can range from translucent to opaque, with varieties like white, black, and fire opals showcasing different characteristics. It is believed to inspire creativity, awaken intuition, and foster emotional clarity. Whether worn as jewelry or cherished as a collector's piece, Opal holds a timeless allure that connects us to the wonders of the natural world. Composition: Hydrated silica. Origin: Most Opals come from Australia, with notable deposits in Ethiopia and Mexico. *SHIPPING* Shipping is always carried out with a tracking code, paying the utmost attention and care to the packaging of the object to preserve its beauty and current condition.
