Antique Style Bi Color Sapphire Ring 4.16 Ct., 18K Yellow Gold

This ring centers on a transparent 4.16 carat oval bi color sapphire, precisely measured at 10.20 by 8.21 by 6.04 millimeters and fashioned with a mixed brilliant cut. The mixed brilliant style combines the scintillation of brilliant facets with a cutting geometry that encourages a generous face-up presence, which is especially effective for showing the subtle color interplay of a bicolor stone. This particular sapphire carries a clarity grade of very very slightly included as evaluated at eye level, meaning the gem is essentially eye-clean and displays only minute internal characteristics that require magnification to fully appreciate. The stone exhibits medium light color saturation and is unenhanced, retaining its natural character and polish quality, which is graded excellent. Origin is a critical element of this sapphire’s appeal, and this stone traces to Ceylon Sri Lanka, a source renowned for producing sapphires with a combination of brightness, attractive pastel tones, and fine crystalline clarity that appeals to connoisseurs and collectors alike.

The provenance from Ceylon amplifies both the aesthetic and market significance of this sapphire. Historically Sri Lankan sapphires are prized for their lively brilliance and often delicate, nuanced hues that differ from the deeper, more saturated tones associated with other sources. For a bicolor sapphire, origin matters because the geology of Sri Lanka frequently yields stones with subtle pleochroism and attractive color zoning where two distinct hues can coexist in a single crystal without compromising transparency. The medium light saturation on this stone allows the bicolor character to be visible and flattering, rather than appearing muddy or overly dark. The fact that this sapphire has received no enhancement increases its rarity and desirability; untreated large, transparent Ceylon sapphires with excellent polish are uncommon in the marketplace, and their natural state is highly valued by educated buyers who prioritize geological origin and authenticity.

Surrounding the sapphire is a halo and complementary diamond work in white round shapes totaling approximately 1.71 carats divided into two groups, one weighing approximately 1.08 carats and the other approximately 0.63 carats. All diamonds are graded F in color and Very Slightly Included at VS1 and VS2 clarity grades, which means they are effectively colorless to the eye and free of visible inclusions under normal viewing conditions. This diamond specification was chosen deliberately to provide a bright, neutral backdrop that enhances the sapphire’s bicolor character without introducing color contamination. The F color grade ensures maximal contrast against the warm yellow gold bezel and prongs while maintaining high brilliance, and VS clarity guarantees that the diamonds contribute pure scintillation rather than competing with the sapphire for visual attention. Set in 14 karat yellow gold, the warm metal tone complements the medium light saturation and the yellowish component of the bicolor stone, harmonizing the overall palette and providing a classical yet contemporary presentation.

At The Natural Sapphire Company we emphasize transparency of origin, accurate gemological description, and the lasting value of natural, untreated gemstones. This ring is an excellent example of those priorities because it pairs an uncommon, untreated Ceylon sapphire with well-matched, high-quality diamonds and a durable 14K yellow gold setting. For the informed buyer, the combination of precise measurements, mixed brilliant cutting to maximize face-up beauty, VVS to eye-level clarity, excellent polish, and documented Sri Lankan origin makes this ring attractive as both a wearable jewel and a collectible piece. We can provide additional imaging, facet-level documentation, and independent gemological analysis on request to support provenance and condition. For care, routine gentle cleaning with mild detergent and a soft brush is suitable, and professional inspection of settings is recommended periodically to ensure long-term security.
