Winton Opal is an Australian boulder opal known for its vivid flashes of color set within rich ironstone matrix. Sourced from the Winton area of Queensland, this opal forms in sedimentary environments where precious opal fills natural fractures and cavities in ironstone. Colors commonly range from bright blues and greens to fiery reds and purples, creating dramatic contrast and depth.
