Three Stone Alexandrite Ring 0.47 Ct., 14K White Gold

This ring centers a transparent 0.47 carat oval alexandrite, its dimensions measured at 5.40 x 4.04 x 2.79 millimeters, cut to a mixed brilliant geometry that combines a carefully proportioned brilliant crown with a precision pavilion to optimize both light return and the material specific color change. The alexandrite displays a striking pleochroic response, shifting from bluish green in cooler, daylight dominant spectra to reddish purple under incandescent balanced spectra, with intense color saturation and an excellent polish that preserves crisp facet junctions and symmetry. Clarity is graded included at eye level, indicating natural internal characteristics that are observable without magnification but that do not compromise structural integrity. No enhancements have been applied to this stone, and its Russian origin is documented, which is significant for alexandrite given the historic mineralogical context of classic Russian material. From a gemological perspective this alexandrite, a chrysoberyl, typically sits within the refractive index range associated with chrysoberyl species and exhibits the low but measurable birefringence that specialists evaluate when assessing facet angles for maximum color separation and optical performance.

The design language of the piece is technically focused and balanced, with the central oval supported by two white pear shaped natural diamonds placed laterally, together weighing approximately 0.20 carats, graded color F and clarity grades VS1 and VS2, which provide high white color and minimal identification of inclusions under 10 times magnification. The pear shaped diamonds are cut and matched to serve as optical flanks to the alexandrite, their pointed termini oriented away from the center to facilitate a visual elongation of the finger and to frame the color change rather than compete with it. All stones are mounted in a secure multi prong setting integrated into an 18 karat white gold framework, the metalwork executed to tight tolerances to ensure seat stability for the delicate mixed brilliant pavilion profile of the center gem. The shank and gallery feature a continuous excellent polish and precise symmetry, chosen to minimize light leakage and to present the alexandrite with maximum apparent depth in both viewing orientations. The choice of 18 karat white gold was made to offer a durable, bright white reflective field that complements the bluish green facet reflections and avoids the color masking that can occur with lower gold content alloys. Craftsmanship notes include careful alignment of facet orientation across the stones, hand setting of the pear diamonds to maintain girdle protection, and a refined gallery that allows light to enter the pavilion and contribute to the alexandrite color response.

At The Natural Gemstone Company we place ethical sourcing and transparency at the core of our procurement and manufacturing practices, and this ring is presented with that commitment in mind. The alexandrite is supplied with documented origin provenance from Russia, and we maintain chain of custody records from mine to market to support that provenance claim, along with the option to supply independent laboratory verification upon request. The natural diamonds are sourced from suppliers who adhere to recognized conflict free protocols and who participate in validated supply chain due diligence processes, including compliance with the Kimberley Process and supplementary supplier attestations. Our 18 karat white gold is procured from refiners that follow responsible sourcing procedures and we make recycled gold options available for clients seeking the highest degree of environmental stewardship. We conduct supplier audits, require documented labor standards, and work with partners who operate within legal and ethical frameworks to reduce the social and environmental impacts commonly associated with extraction. For technically oriented clients we can provide detailed documentation of the gemological grading observations, photographs of the stone under multiple lighting conditions to illustrate the color change, and reports on the metal composition and finishing tolerances, all in support of an informed acquisition that aligns with both aesthetic and ethical priorities.
