11.63 Ct. Cabochon White Opal from Australia

One beautiful translucent 11.63 carat oval shape White Opal is presented here, with precise dimensions 22.64 by 15.54 by 4.37 millimeters, a traditional cabochon cut, a clarity grade of very slightly included evaluated at eye level, near colorless body color intensity, and an excellent polish. The gem is unenhanced, with no treatments applied, and its documented origin is Australia, a source renowned for high quality White Opal. As seen in the provided images, the stone displays a clean, milky background typical of White Opal, with subtle internal characteristics that manifest as fine, warm toned inclusions that do not dominate the visual experience, but rather add character and proof of natural formation. The cabochon dome has been executed to enhance the stone s translucency and surface luster, providing smooth curvature that maximizes light return and tactile appeal. These measured specifications and the absence of enhancement are the fundamental data points that an educated buyer will use to evaluate suitability for a collector s cabinet or a bespoke jewelry commission.

To understand the grading terms in context, White Opal refers to opal whose body color is light to near colorless, a category distinct from black or crystal opal where play of color and body tone are evaluated differently. Translucent description indicates that light penetrates into the stone and diffuses internally, creating the soft, glowing appearance that makes White Opal desirable for certain designs. The clarity grade very slightly included, assessed at eye level, means that inclusions are present but minor in size or contrast, and they are not expected to significantly weaken the stone structurally or visually at normal viewing distances. Near colorless intensity provides a neutral canvas that complements a range of metal choices and mounting styles, and an excellent polish ensures optimal surface finish, reducing light leakage at the surface and enhancing perceived depth. The fact that the opal is unenhanced increases its long term value to discerning purchasers, because no stabilization, dye, impregnation, or resin treatments have been used to alter appearance or durability. Buyers should be aware that opal is a hydrated silica, and while many Australian opals show excellent stability, sensible care is recommended to avoid sudden temperature changes, prolonged exposure to strong solvents, or ultrasonic cleaners that can risk microfracturing or surface damage.

From the perspective of value and practical use, an 11.63 carat oval cabochon White Opal of these dimensions occupies a useful niche between collectible specimens and wearable gemstones, offering both presence and versatility. The size 22.64 by 15.54 by 4.37 millimeters is well suited to creating a striking pendant focal or a statement ring, particularly when set in a protective bezel to shield the edge and minimize exposure to knocks. For settings, yellow gold will warm and accentuate any faint warm inclusions, while white gold or platinum will emphasize the cool, near colorless ground and provide a contemporary contrast. The cabochon cut supports consistent play with light across the surface and is the preferred form to showcase translucency, while the excellent polish aids in reducing the appearance of surface imperfections and increases the immediate visual appeal.
