2.90 Ct. Boulder Opal from Australia

I am pleased to introduce a striking Boulder Opal offered by The Natural Gemstone Company, one beautiful opaque 2.90 carat freeform shape multi color opal that showcases the natural artistry of Australian opal fields. This gem measures 13.14 by 8.62 by 3.28 millimeters, and it is fashioned in a tablet cut that emphasizes the broad, colorful surface with a comfortable thickness for setting. The opal displays a medium intense color intensity, and it has an excellent polish that gives the surface a lively, glass like finish. Enhancement, none, this stone is completely natural and untreated, and its origin is Australia, a source renowned for producing the finest boulder opal specimens. As a Boulder Opal, it retains a thin layer of ironstone backing that not only anchors the opal but also supplies attractive contrast and stability, making this piece uniquely suited to both collectors and designers who appreciate authentic natural character.

Visually this multi color opal is captivating, with a dynamic play of color that shifts as the stone is turned, revealing flashes of fiery red, vivid green, deep blue, and warm orange across its tablet shaped face. The freeform outline allows these colors to flow organically, creating patterns that suggest painterly streaks and patches rather than rigid symmetry, an effect that appeals to anyone seeking a one of a kind centerpiece. The medium intense color intensity means the colors are strong enough to be immediately noticeable under normal lighting, yet retain a nuanced depth that rewards closer inspection. The excellent polish enhances luster and clarity of the color play, while the ironstone matrix along the edge gives a rich, earthy frame that accentuates the opal face. Because this is an opaque boulder opal, light behavior differs from transparent opals, offering a bold and robust visual presence that translates well into wearable pieces that catch the eye from a distance and reveal detail up close.

For design and wearing suggestions, this freeform tablet is extraordinarily versatile, and it can be set as a striking pendant, an elegant cocktail ring, a bespoke brooch, or a distinctive pair of matched pieces if you commission a complementary companion stone. The ironstone backing of a Boulder Opal lends itself beautifully to bezel settings that celebrate the stone contours, and it can also be secured with low profile prongs for a more contemporary look, care being taken to protect the thin opal face. Metals like warm yellow gold enhance the red and orange flashes, while white gold and sterling silver provide a crisp backdrop that makes greens and blues sing, so your choice of metal can help emphasize the palette you most love. Because this opal is already expertly cut and polished, it is ready for immediate setting, or for a custom design if you prefer a unique mounting tailored to the stone profile. Collectors will appreciate that there are no enhancements, and designers will value the natural textures that only a true Australian Boulder Opal provides.

As your gemstone partner, The Natural Gemstone Company is happy to assist with additional imagery, close up views, and guidance on setting and care to ensure lasting enjoyment. For everyday care, avoid exposure to prolonged heat, harsh chemicals, and ultrasonic cleaners, and clean gently with warm water, mild soap, and a soft brush or cloth, storing the opal separately to prevent contact with harder stones. If you would like advice on matching this piece with a particular ring size, pendant design, or bespoke commission, please reach out to our team for recommendations and options for secure shipping and professional setting partners. This 2.90 carat tablet cut Boulder Opal is a unique treasure from Australia, ready to become the focal point of a custom creation or a cherished addition to a curated collection, and we look forward to helping you bring its natural color and character to life.
