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

One beautiful translucent 1.89 carat oval shape multi color opal, dimensions 11.43 x 8.15 x 4.68 mm, cabochon cutting style, white opal type, from Ethiopia. This specimen is cut as a high dome cabochon with precise oval symmetry, the dome apex aligned to maximize play of color across the surface. Clarity is eye clean as evaluated at eye level, color intensity rated medium to preserve balance between body tone and spectral flashes, and the polish is excellent producing a glass like surface free of polish haze. No enhancement has been applied, the material is in natural state, and the weight to dimension profile yields a substantial feel for 1.89 carat without excess thickness. The Natural Gemstone Company presents this opal with full provenance and technical evaluation to appeal to connoisseurs who prioritize natural structure and cutting technique.

The unmatched sparkle of this opal derives from its internal silica sphere lattice rather than from faceting geometry, the regular close packed arrangement acting as a natural diffraction grating. Sphere size distribution defines the dominant wavelength of the play of color, while the translucent white body allows light to penetrate multiple layers, undergo constructive interference, and re emerge as vivid spectral patches and flashes. The cabochon dome is calibrated to optimize the light path, increasing internal reflection and angle dependent color shifts, while the excellent polish minimizes surface scattering that would otherwise dilute contrast. The eye clean clarity enhances the visual depth, enabling crisp, separate color patches rather than diffuse glows, and the medium body intensity maintains strong color saturation without masking the multi color fire. Because the cutting preserves the continuous curved window rather than breaking light into facets, the resulting optical effect is a dynamic, living sparkle that shifts with viewer position and light angle in ways that faceted gemstones cannot replicate. For technical buyers seeking an opal whose microstructure, cutting proportions, and finishing techniques have been executed to reveal maximum optical performance, this Ethiopian white opal from The Natural Gemstone Company offers a rare combination of engineered cutting, verified clarity, and natural, untreated play of color.
