1.75 Ct.Tw.Total Carat Weight Cabochon Opal Pair from Australia

These two boulder opals began their story deep in the ancient ironstone ridges of Australia, where silica rich waters settled into cracks and cavities over millions of years, freezing flashes of color into stone. Miners working the outback brought these small miracles to light, each rough piece revealing a different chapter of the landscape, a ribbon of green here, a fiery red there, a flash of electric blue under a sunlit turn. The Australian origin of these gems is more than a place of provenance, it is a lineage of geology and culture, a reminder of how land and story conspire to create something rare. Boulder opal is unique because its precious opal weaves through a dark ironstone matrix, giving a depth and contrast that amplifies play of color, and communities across the country have long admired and respectfully revered these stones for their beauty and connection to place.

At The Natural Gemstone Company we honor that journey through careful cutting and finishing, transforming those rough flashes into a matched pair that is ready to wear. These two opals are oval multi color cabochons, weighing 0.84 carats and 0.91 carats, with dimensions of 8.00 x 6.22 x 1.94 mm and 8.12 x 6.07 x 2.37 mm respectively, showing intense color intensity and an excellent polish. The pieces are enhancement doublets, a skilled technique where a thin slice of precious opal is backed to the natural ironstone or a dark base to stabilize and magnify the color, making the play of color sing while retaining the spirit of the boulder matrix. The cabochon cut accentuates the stone s luminous patches and flashes, creating a living surface that shifts as you move it. These paired opals make an exceptional option for earrings or a complementary set in a crafted pendant, offering both history and wearable art. For collectors and designers seeking a responsibly sourced, characterful gemstone, these Australian boulder opal doublets from The Natural Gemstone Company are ready to continue their story in your next creation, and we are happy to provide additional photos, matching suggestions, and handling guidance to ensure their beauty is preserved.
