11.39 Ct. Cabochon White Opal from Australia

If you are searching for a singular center stone that ends the search for the perfect engagement ring, or if you are a collector seeking a rare and expressive specimen, this opal answers both needs with quiet confidence. Many clients come to us longing for a gem that combines presence and personality, a stone that reads as elegant every day and extraordinary under special light. This oval white opal has the size and character to become a defining piece, whether set in a classic solitaire, embraced by a halo of diamonds, or crafted into a museum quality pendant. From the first conversation through selection and final setting, our goal is to match you with a gem that not only meets your criteria for beauty and authenticity, but exceeds it in emotional impact, durability of wear, and provenance.

This is one beautiful opaque 11.39 carat oval shape multi color opal, with dimensions of 19.28 by 14.68 by 6.27 millimeters. The stone is a White Opal, cut en cabochon to maximize the surface play of color, and evaluated at eye level as very slightly included, which means the clarity is excellent for practical wear with details that do not distract from the overall appearance. The color intensity is medium, offering a balanced display of color flashes that shift gently with movement. The polish is excellent, giving the dome a smooth, reflective finish that is a joy to touch and to behold. There are no enhancements to this gem, and the origin is Australia, which is world renowned for producing opals of consistent quality and natural beauty.

In everyday viewing the opal presents a soft milky base that allows delicate flashes of green, hints of yellow, and occasional blue and orange to appear like brushstrokes of light beneath the surface. Because it is an opaque White Opal, the play of color reads against a luminous backdrop, making the hues pop without overwhelming the eye. The oval cabochon shape is an ideal choice for this material, offering a classic silhouette that flatters many setting styles, while the generous 11.39 carat weight ensures presence without being cumbersome. The multi color character means that the stone will harmonize with both warm and cool metal choices, and it will pick up and reflect surrounding tones to complement skin tones and accompanying gemstones. When you lift the gem into light, the colors migrate and rearrange in a way that is quietly mesmerising, offering a personal show that changes across moments and seasons.

For an engagement ring, this opal is a romantic and meaningful choice, but it does require thoughtful setting and care to remain beautiful for a lifetime. We recommend a protective bezel or a low profile setting that keeps the dome from direct impact, and choosing metals and design elements that cradle the stone rather than expose it to knocks. Opal has a moderate hardness and a delicate internal structure compared with traditional diamonds, so it is ideal for wearers who appreciate beauty and who will take a mindful approach to daily activities. For cleaning, gentle soap and water with a soft cloth is best, avoiding ultrasonic cleaners and harsh chemicals. Store the opal away from direct heat and extreme dryness, and if the stone will be in very dry conditions, occasional exposure to a slightly humid environment can help maintain its stability. For collectors, the natural, unenhanced origin and the Australian provenance add to long term desirability and make this piece a worthy addition to a curated cabinet of gems.

At The Natural Gemstone Company we take pride in sourcing stones that combine authenticity, aesthetic appeal, and responsible origin, and this oval White Opal exemplifies those qualities. We are available to discuss custom design options, to advise on the best setting for protection and beauty, and to provide additional images or viewing under different lighting if you wish to see how the color play responds to movement and illumination. If you are ready to move forward, we can assist with bespoke mounting suggestions that preserve the gem while showcasing its multi color spectacle, or we can prepare secure shipping and certification details to ensure complete confidence in your purchase. Let this Australian opal conclude your search, and allow us to make the experience of acquiring and wearing it effortless and deeply satisfying.
