This Australian opal doublet displays strong red dominant multicolor fire with vibrant flashes of orange, yellow, green, blue, teal, purple, and pink across the surface. Presented as a smooth cabochon, the stone offers excellent visual presence and is well suited for a statement pendant necklace or high value October birthstone jewelry design. Constructed from a thin layer of genuine precious Australian opal bonded to a natural ironstone backing, the doublet format enhances color contrast and depth, allowing the red dominant fire to show with clarity and intensity.
