1.85 Ct. Multi Color Cabochon White Opal (Light Opal) from Brazil

This White Opal Light Opal from Brazil presents as a translucent, multi color oval cabochon weighing 1.85 carats, with dimensions 9.94 by 7.84 by 3.56 millimeters. The carat weight in this size range is a material determinant of value and rarity, because larger intact white opal material with clean body tone and even translucency is less common in the market. At 1.85 carats the piece maintains a balanced mass to surface area ratio, allowing a 3.56 millimeter height that supports a moderate domed profile, which in turn optimizes internal light scattering and play of color without compromising stability. Clarity is graded very slightly included at eye level, a designation that indicates minimal internal features that do not detract from face up appearance, and contributes positively to market desirability when combined with the stone s excellent polish and lack of enhancement. The light color intensity yields a classic white opal body tone, while the observed multi color play provides vibrant flashes across the blue, green and warmer spectrum, indicative of well-aligned silica spheres and effective lapidary orientation.

From a technical lapidary perspective the cabochon cutting style has been executed with precise proportions to maximize color return and wearability. The oval outline is symmetrical, the dome curvature is controlled to reduce stress concentrations, and the excellent polish minimizes surface diffusion, allowing the underlying fire to present crisply. For collectors and designers who assess material by both gemological constants and practical setting considerations, note that opal specific gravity typically approximates 2.10 to 2.20 and Mohs hardness is in the 5.5 to 6.5 range, factors that inform bezel or protected setting choices to preserve the stone s surface. The absence of enhancements further confirms natural origin and contributes to long term value retention. The Natural Gemstone Company offers this White Opal Light Opal as a technically superior specimen for connoisseurs who value an optimal combination of carat weight, cabochon craftsmanship, translucency and natural play of color, making it a desirable and relatively rare offering within its size class.
