How Old is Opal?
Opals, the mesmerizing gemstones with their iridescent play of color, are relatively young compared to other gemstones. They are typically formed within the last 5-30 million years, dating back to the Miocene and Pliocene epochs. These epochs witnessed the rise of grasses and the cooling of Earth’s climate, creating ideal conditions for opal formation in sedimentary rocks. While some opals may be as young as 1,000 years old, the oldest known specimens date back millions of years, providing a glimpse into Earth’s geological history.
