4.17 Ct. Orangish Yellow Cabochon Sapphire from Ceylon (Sri Lanka)

This specimen is a translucent 4.17 carat oval orangish yellow sapphire, measuring 10.38 by 8.07 by 5.84 millimeters, presented in a classic cabochon cut. The oval proportions yield a length to width ratio of approximately 1.29, producing an elegant elongation that suits both traditional and contemporary mounting styles. The cabochon profile is deliberately high, with the 5.84 millimeter depth contributing to a pronounced dome that enhances internal light transmission and imparts a warm glow through the body of the stone. Clarity has been evaluated as very slightly included at eye level, indicating small internal features that do not materially interrupt the stone face up, preserving translucency and allowing the orangish yellow hue to read with consistent saturation. Color intensity is described as intense, the saturation and tone remain uniform across the dome, and the heat treatment applied is a standard enhancement used to stabilize and intensify natural color while improving apparent clarity. Origin is Ceylon Sri Lanka, a source renowned for producing sapphires with lively tone and enduring desirability.

From a craftsmanship perspective, the cutting and polish of this cabochon demonstrate careful attention to proportion and surface finish, the polish is excellent producing a glassy sheen across the dome and crisp specular highlights at the apex. The cutter has retained optimal thickness to balance durability with pleasing light diffusion, the dome curvature and symmetry are well centered, and the transition to the base maintains a clean profile suitable for secure bezel or low prong settings. These technical choices enhance the perceived color depth and ensure the gem performs well in wearable jewelry. At The Natural Sapphire Company we document this stone as heat treated and originating from Ceylon Sri Lanka, and we provide guidance on setting and care to maintain its appearance. For collectors and connoisseurs who prioritize precise proportions, stable enhancement practices, and provenance, this 4.17 carat cabochon offers a substantial and characterful example of a richly colored Ceylon sapphire, suitable for refined jewelry projects or as a standout specimen in a curated collection.
