Solitaire Bi Color Sapphire Ring 5.52 Ct., 10K Yellow Gold

This ring centers a transparent, bi color sapphire weighing 5.52 carats, cut in a classic emerald shape, with exact dimensions of 10.63 by 8.54 by 5.94 millimeters, offering a commanding presence and refined proportions. The stone exhibits vivid color saturation and an excellent polish, and it is graded as very very slightly included when evaluated at eye level, which confirms exceptional clarity for a stone of this size. The pavilion depth of 5.94 millimeters relative to the average of the length and width produces a depth that is approximately sixty two percent, a proportion that balances face up appearance with internal light return in an emerald cut. The bi color disposition, showing a lively transition between blue and green tones across the table, is retained and highlighted by the step facet architecture of the emerald cut. The Natural Sapphire Company presents this stone in a mounting that complements the gem without competing with it, preserving the integrity of the cut and the purity of the color.

The origin of this sapphire, Madagascar, plays a central role in the gemology and desirability of the piece, because Madagascar deposits are renowned for producing material with intense, saturated color and well developed crystal habits amenable to clean cutting. Corundum from Madagascar often carries a combination of iron and titanium trace elements that interact within the crystal lattice to produce strong blue and green tones, and in bi color material the spatial distribution of these trace elements creates distinct color zoning. This zoning, when preserved and oriented by a skilled cutter, yields a dynamic face up appearance that shifts with viewing angle and light source, an effect that collectors and connoisseurs prize. Madagascar provenance also reflects a geological history of late stage pegmatitic and metamorphic processes that form larger, gem quality crystals, which is one reason why the presence of a five carat plus, transparent, very very slightly included emerald cut sapphire is especially noteworthy.

From a cutting and faceting perspective, the emerald cut selected for this sapphire is a deliberate technical choice intended to maximize the gems color and clarity characteristics while maintaining a clean, architectural aesthetic. The step facet pattern produces broad, flat planes that emphasize color fields rather than scintillation, which is ideal for bi color material where color transition and depth are the principal points of interest. The cutter maintained an even crown and pavilion symmetry to ensure that the table plane reads the color zones without introducing unwanted windowing or dead zones. The excellent polish enhances facet junction crispness and allows the sapphire to exhibit a saturated face up color while preserving the stones internal clarity. The combination of a measured depth ratio, a well proportioned table, and meticulous facet alignment produces a stone that reads larger than its carat weight might suggest, because the table and step facets present a generous, luminous face that concentrates color in a pleasing manner.

The setting is executed to both protect and showcase the sapphire, with a yellow gold mounting that provides a warm counterpoint to the cool blue and green tones of the gem, and with a four prong crown that secures the stone while leaving the pavilion open for light entry and escape. The shank and gallery are crafted to provide structural integrity and comfortable wear, with slender, flowing shoulders that direct attention to the stone without creating visual interruption. The open under gallery facilitates cleaning and maximizes light return, while the prongs are shaped and polished to minimize metal shadowing across the table. The overall result is a ring that reads as an integrated gemological statement, where Madagascar origin, precise emerald cut proportions, vivid color saturation, superior polish, and considered gold mounting converge into a piece that reflects the standards of The Natural Sapphire Company. For clients who value provenance and technical craftsmanship in equal measure, this ring represents a thoroughly considered option, and we can provide additional documentation on origin and cutting specifications upon request.
