1.85 Ct. Cabochon White Opal from Brazil

This translucent White Opal, sourced from Brazil and presented by The Natural Gemstone Company, is an oval cabochon weighing 1.85 carat, with dimensions of 9.94 by 7.84 by 3.56 millimeters. The gem has been expertly preformed and finished as a classic cabochon to maximize its multi color play, with a smooth domed profile that balances a visible flash with structural stability. Clarity is graded very slightly included when examined at eye level, indicating minimal internal features that do not interrupt the visual field, while the light color intensity provides a soft opaline body that allows subtle spectral colors to register across the surface. There are no enhancements applied to this stone, and the polish is excellent, reflecting precise lapidary control over lap speed, abrasive sequence, and final buff to achieve a high gloss that enhances color transmission without masking the opal matrix. The oval outline and measured proportions were chosen to optimize yield from the rough material, preserving thickness where color broadness is present, and maintaining symmetry for straightforward setting.

The weight of 1.85 carat is a significant factor in the valuation and rarity profile of this White Opal, because opal value scales with carat weight and with the presence of coherent color play across greater surface area. At nearly two carats this cabochon offers a rare combination of wearable size and intact color zones, making it well suited for center settings in rings and pendants where the mass can be appreciated. From a craftsmanship perspective, retaining this weight required careful orientation during preforming to align color seams, conservative trimming to avoid thinning the color layer, and a controlled dome height near 3.56 millimeters to balance resilience with optical performance. For collectors and designers who value natural state material, the absence of treatment increases provenance value and reduces long term maintenance risks. The Natural Gemstone Company provides this opal as a calibrated example of Brazilian White Opal material that combines technical cutting discipline, measurable proportions, and a collectible weight that enhances both aesthetic presence and market desirability.
