Solitaire Bi Color Sapphire Ring 1.57 Ct., 18K Yellow Gold

This ring centers on a transparent 1.57 carat cushion shape bi color sapphire, precisely measured at 6.98 by 4.94 by 4.82 millimeters, cut to a mixed brilliant geometry that marries pavilion brilliance with a carefully faceted crown. The mixed brilliant cut on a cushion outline typically integrates a traditional brilliant facet pattern on the pavilion with step influenced facets near the girdle and crown, and that hybridization is evident in the stone before you. The table proportion has been optimized to balance scintillation with face up color, while the crown angles are tuned to disperse light through the slightly rounded corners inherent to the cushion profile. Facet junctions exhibit crisp meets, and the symmetry of the facet arrangement enhances optical return without sacrificing the soft, classic silhouette that defines a cushion outline. This precise faceting strategy yields a controlled play of light that is technically satisfying to connoisseurs who track facet counts and angular relationships, and it produces a clean, lively face up appearance that pairs well with the restrained metalwork of the mounting.

Clarity and color are central to the gemological appeal of this piece, the sapphire carrying a clarity grade of very slightly included when evaluated at eye level, which denotes the presence of small internal characteristics that do not interfere with transparency or brilliance under normal viewing. These inclusions are consistent with natural Tanzanian material, and they affirm the stone as untreated, as the sapphire has no enhancement. Color presentation is in the medium intense range for saturation, a specification that in practice translates to a lively color identity without tipping into overly dark territory, preserving both depth and vibrancy. The bi color nature of the sapphire manifests as a perceptible shift in hue across different viewing angles and light sources, which is characteristic of pleochroic sapphires and particularly desirable in material from certain Tanzanian deposits. The excellent polish across the crown and pavilion surfaces contributes to clean facet reflections and unimpeded light transmission, further amplifying the mixed cut strategy and allowing the medium intense saturation to read consistently under varied lighting.

The mounting is executed entirely in 14K yellow gold, chosen to complement the warm green to yellow green tones that a Tanzanian bi color sapphire can display. The setting employs a four claw prong architecture that secures each corner of the cushion profile, providing mechanical stability while minimizing obstruction of the pavilion and table, which preserves light intake from multiple angles. The prong heads are tapered and rolled to a profile that reduces sharp contact with clothing and daily wear surfaces, and the prong cups are deep enough to cradle the girdle without overbearing the stone or obscuring its pavilion facets. The head construction and gallery are engineered to distribute stress away from the girdle, and internal solder joints are ground and polished to present uninterrupted lines where the head meets the shank. The shank itself is a slender, rounded band with a comfort fit profile, finished to a high polish that complements the excellent polish of the sapphire, and the overall metalwork reflects careful control of proportions so that the mounting reads as visually light, structurally sound, and ergonomically comfortable.

The design of this ring intentionally balances elegance with functionality, marrying refined aesthetic restraint with practical considerations for daily wear. The low to mid profile of the head reduces the risk of catch, while the open prong orientation allows routine cleaning access and inspection of the pavilion, which is important for a collector assessing the mixed brilliant facets and natural internal features. The choice of 14K yellow gold provides an advantageous hardness to support prongs over time, while still delivering a warm, classic backdrop that accentuates the medium intense bi color presence. For specialists and informed buyers, The Natural Sapphire Company offers provenance details confirming Tanzanian origin, and the untreated nature of the stone enhances long term color stability and value. The overall result is a piece that reads as understated and sophisticated in photographs and in hand, yet engineered with measured practicalities that preserve the integrity of the sapphire and the comfort of the wearer, making this ring an exemplary combination of technical gemological merit and considered jewelry craftsmanship.
