2.19 Ct. Cabochon Boulder Opal from Australia

This opal is presented as a 2.19 carat, oval shaped, multi color Boulder Opal, with measured dimensions of 11.01 x 7.50 x 3.98 mm, and a cabochon cut. The material is opaque in body tone, and it displays intense color intensity across a warm ground with varied play of color. The piece is offered as an assembled doublet, a disclosed enhancement that affords greater stability and contrast, and it carries an excellent polish that preserves surface smoothness and optical responsiveness. Origin is Australia, and the combination of weight and face up dimensions produces a substantial visual footprint, making the stone noticeably larger than many standard sized opals in this weight range. The oval outline and cabochon dome have been executed to present a broad, continuous surface area for the color play to manifest, and the careful shaping maximizes the apparent size when mounted in a jewelry setting.

Clarity for this specimen is best described in terms relevant to opal material and finished opal products, with emphasis on surface condition, color distribution, and the absence of disruptive fractures or pits. Although the opal is opaque, the surface is clean and uniformly finished, and the quality of the polish allows the iridescent patches to read crisply at typical viewing distances. The opal displays a multi color palette that reads as intermingled flashes rather than isolated pinpoints, and the intensity of the color appears consistent across the oval table, which contributes to a cohesive appearance when worn. The doublet construction enhances the depth and saturation of the play of color by providing a dark backing, and the cabochon profile permits wide angle viewing of the color change, which is an important attribute for a statement piece intended to attract visual attention from a distance. The overall result is a stone whose optical performance is driven by a combination of size, surface finish, and even color presentation.

From a practical perspective the dimensions and surface quality make this Boulder Opal doublet a straightforward candidate for a statement setting, especially in solitary designs where the opal is intended to be the central visual element. The 11.01 by 7.50 millimeter face and 2.19 carat weight are well suited to a pendant focal, a mid to large size ring, or a centerpiece in a cuff or brooch where the stone can be mounted with protective bezel or partial bezel construction to shield the stone edge. Given the assembled nature of doublets, standard recommendations for care apply, including avoidance of prolonged exposure to water and steam, restraint from abrupt temperature changes, and careful protection from hard impacts that might separate layers. Setters should account for the backing when planning prongs and seats, ensuring that any setting work supports the slab and does not place direct stress on the opal layer. The Natural Gemstone Company has documented the described specifications and the disclosed enhancement, and the listing reflects the physical characteristics, country of origin, cut and finish, and optical description. Taken together, the size, disciplined surface clarity, intense color intensity, and the polished cabochon form a balanced presentation, and these attributes make the stone particularly appropriate for a statement piece where confident presence and reliable optical delivery are the primary objectives.
