11.12 Ct. Multi Color Cabochon White Opal (Light Opal) from Ethiopia

This 11.12 carat pear shape White Opal, Light Opal, from Ethiopia is a standout example of natural opal beauty, presented as a well executed cabochon with dimensions of 24.42 x 17.99 x 5.85 mm. Translucent in body tone with intense color intensity, the gem shows vibrant flashes of green, red, and blue across its surface, supported by an excellent polish that maximizes luster. The clarity is graded as slightly included, evaluated at eye level, a common and acceptable characteristic in opals of this size that does not detract from the overall visual impact. There is no enhancement, confirming that the play of color is wholly natural. For the educated buyer, the combination of size, origin, untreated status, and strong play of color establishes clear market value, while the Ethiopian provenance is meaningful because it is associated with well documented deposits that yield high quality light opals.

The cabochon cutting style and pear shape work together to amplify the opal’s inherent light reflecting properties. The domed cabochon profile presents a smooth convex surface that allows light to enter and interact with the silica spheres inside the opal, producing broad, well distributed flashes rather than fragmented sparkle. The moderate dome height preserved in this cut maintains internal diffraction pathways, so color patches shift fluidly as the angle changes, and the pear outline concentrates larger color patches toward the tip for dramatic movement when mounted. Excellent polish reduces surface scattering and increases specular reflection, making the play of color appear cleaner and brighter to the observer. Slight inclusions, observed at eye level, are internal and do not interrupt the continuity of color play, and they can also serve as natural fingerprints that confirm authenticity. The Natural Gemstone Company offers this stone with clear grading details and transparent origin information, making it a strong choice for collectors and designers seeking a sizable, untreated White Opal, Light Opal, that performs well in both display and jewelry settings.
