4.01 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This transparent 4.01 carat oval blue sapphire from Ceylon is a superb example of classic Sri Lankan material, with dimensions of 11.33 by 7.97 by 4.99 mm, and a mixed brilliant cut that balances scintillation and color face up. The cut has been executed to maximize light return across the crown while preserving the deep, intense blue saturation that collectors prize, and the excellent polish ensures crisp facet junctions and lively brilliance. Clarity is graded very very slightly included evaluated at eye level, which for an educated buyer means the stone reads as essentially eye clean and reveals only minimal inclusions under close inspection, preserving both transparency and apparent depth. The combination of intense color intensity and a very clean eye appearance is rare in this size, and contributes substantially to the gemstone value.

This sapphire has been heat treated, a widely accepted enhancement that enhances blue tone and clarity without compromising stability, and it carries the esteemed heritage of Ceylon origin, known historically for producing velvety and cornflower blues prized by royalty and sacred traditions. Sapphires from Sri Lanka have a long provenance in ceremonial and devotional jewelry, and have traditionally been used as protective talismans, symbols of wisdom, and center stones in regal rings and pendants. For the discerning buyer, this stone offers that same lineage, combining traditional character with modern cutting to deliver a wearable gem for an engagement ring or a museum quality piece for a collection. At The Natural Sapphire Company we source and evaluate each sapphire with rigorous attention to origin, treatment, and optical performance, ensuring clarity assessments and measurements are accurate and transparent. If you are considering this 4.01 carat Ceylon sapphire for a bespoke setting, our gemologists can advise on mounting styles that showcase the length to width ratio and mixed cut reflections, while maintaining the classical heritage that makes Sri Lankan sapphires so enduringly desirable.
