11.12 Ct. Multi Color Cabochon White Opal from Ethiopia

This translucent, pear shaped White Opal weighs 11.12 carat and measures 24.42 x 17.99 x 5.85 mm, offered by The Natural Gemstone Company. This Ethiopian opal displays intense color intensity with multi color play, and is a solid natural gem with no enhancement. The gem is cabochon cut and evaluated at a clarity grade of slightly included at eye level, a typical and acceptable characteristic for opals of this size and translucency that does not detract from the stone's visual impact. An excellent polish brings forward a clean, reflective surface that complements the internal play of color, while the translucency allows internal diffraction to be seen from multiple angles. For an educated buyer seeking provenance and integrity, origin from Ethiopia is significant because Ethiopian fields produce a distinctive, bright play of color and are currently among the most important sources of high quality White Opal, making this specimen desirable both for collectors and for those commissioning fine jewelry.

The cabochon pear shape is intentionally chosen to maximize the opal’s inherent light interaction, the domed profile of the cabochon introduces a continuous curved surface that functions like a lens, allowing light to penetrate, refract, and return as vivid spectral flashes. The gentle dome depth over the broad face ensures sufficient thickness of opal material for the diffraction of light from the internal silica spheres that create play of color, and the pear outline provides graceful variation in viewing angles so different color patches become dominant as the stone or the wearer moves. The excellent polish enhances surface reflection and aids visual clarity, while the slightly included clarity grade, when set with proper orientation, will be visually minimized and can add character without compromising the gem’s brilliance. From a practical perspective, this solid, untreated White Opal benefits from careful setting design to protect edges and to orient the dome for optimal color display, and collectors will value the combination of size, intense multi color play, natural origin, and meticulous finishing. The Natural Gemstone Company stands behind the stated characteristics, offering this Ethiopian White Opal as a fine example of how cut, polish, and provenance together elevate an opal’s light performance and market value.
