Three Stone Bluish Green Sapphire Ring 2.16 Ct., 18K Yellow Gold

This ring centers on a transparent 2.16 carat oval bluish green sapphire, precisely measured at 8.34 by 7.04 by 4.86 millimeters. The stone is cut to a mixed brilliant faceting scheme, combining a brilliant style crown with a modified pavilion geometry to optimize both scintillation and saturation response. The oval outline preserves a balanced length to width relationship that allows for a generous crown and table, while the pavilion has been calibrated to a depth that yields an overall stone depth of approximately sixty three percent of the mean diameter, a proportion that maintains strong light return without sacrificing the vivid body color. The mixed brilliant execution produces a dynamic interplay between larger crown facets that display color and smaller pavilion facets that create pinpoint fire, an arrangement that emphasizes the stone character while delivering lively face up brilliance across a range of lighting conditions. The cutting emphasizes symmetry and facet alignment, and the girdle treatment provides secure seating within the head while minimizing extraneous mass that would reduce apparent brightness.

Clarity and color specification are engineered for performance. The sapphire has been evaluated at eye level and assigned a clarity grade of very slightly included, indicating minor internal characteristics that do not impede visual transparency or detract from the saturated color when viewed in normal wear. The color is described as vivid with bluish green tonality, a saturation and hue balance that reads as a rich teal in daylight and may present deeper green notes under incandescent lighting, a pleochroic response typical of sapphire crystal structures that contain balanced trace elements. The polish is excellent, producing crisp facet junctions and a smooth finish that enhances surface reflectivity and contributes materially to overall luster. The gem’s origin is Tanzania, a provenance that is associated with gemstones showing robust color saturation and clean crystal habit, attributes that have been preserved through careful cutting and finishing to showcase the sapphire’s intrinsic material quality.

Flanking the center stone, the mounting incorporates two white pear shaped natural diamonds whose combined weight is approximately 0.20 carats. Each side stone is shaped and faceted to complement the oval center, with a pear outline that tapers the visual mass toward the shoulders and reinforces the ring geometry. The diamonds are graded Very Slightly Included at the VS1 and VS2 levels, delivering eye clean appearances while retaining strong structural integrity for bezel or prong setting. The color grade F places these diamonds in the near colorless category, providing a crisp white contrast to the sapphire without introducing warmth that would alter the perceived tone of the center gem. The faceting on the pears is executed to produce tight scintillation and return, creating lively flashes that articulate the ring silhouette and frame the vivid sapphire. The total diamond placement is calibrated to create optical balance, with pavilion angles and crown heights matched to the center stone elevation to ensure even light performance from the head down through the gallery.

The mounting is executed in 10K yellow gold, selected for its warm hue that complements and intensifies the bluish green sapphire tone and produces an elegant contrast with the white diamonds. The head is constructed with secure prong work to hold the oval in a four prong configuration that elevates the stone while providing unobstructed crown exposure to light. The side diamonds are set in a tapered shoulder arrangement, with their girdles closely aligned to the ring shank to maintain structural symmetry and comfortable wear. The under gallery is open and engineered to allow maximum light ingress to the pavilion facets, enhancing the stone interaction with ambient light and facilitating cleaning and inspection. The shank is rounded for ergonomic comfort and polished to an excellent finish consistent with the gemstone polish, while the joints and prong shoulders are hand finished to precise tolerances to ensure long term durability. This combination of material selection, faceting strategy, and hand setting produces a ring that functions as a deliberate statement piece, exuding quiet confidence through technical excellence, measured proportions, and considered contrast. The Natural Sapphire Company stands behind the design and craftsmanship, providing provenance documentation and quality assurance, and offering this ring as an articulation of refined taste for the buyer who appreciates detailed gemological attributes and the visual authority of a well executed center sapphire.
