3.79 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This pear shape blue sapphire from The Natural Sapphire Company presents at first glance as a classic and refined gem, combining notable size with superb optical appeal. Weighing 3.79 carats, and measuring 11.36 by 7.30 by 5.94 millimeters, this stone occupies a scale that reads as both wearable and impressive for a single center gem. The gemstone is transparent, with a vivid color intensity that reads as a saturated, lively blue consistent with high quality Ceylon origin material, and it has been heat treated, which is a standard and accepted enhancement in the sapphire trade. The mixed brilliant cut, applied to this pear shape, and the excellent polish work together to present crisp facet junctions, clean reflective planes, and a lively surface return that enhances the stone visually in every lighting condition. At eye level the clarity is assessed as very very slightly included, which means the inclusions are minor and do not interfere with the overall transparency or the immediate visual impact of the stone, preserving its value and desirability for an educated buyer.

The geometry of the faceting is central to the gemological story of this sapphire, and the mixed brilliant approach has been chosen intentionally to maximize light play. In practical terms this means the cutter has combined the angular, step influenced pavilion and crown planning that supports even distribution of contrast and the smaller, more numerous brilliant facets that increase scintillation and return. The pear outline provides a natural pathway for light, guiding rays from the rounded base through the elongated silhouette to the tapered point, and the precise proportions represented by the measurements ensure that light is neither lost through an overly deep pavilion nor diluted through a shallow table. The facet architecture yields a dynamic interplay between bright flashes of returned light and darker contrast areas that define the gem form, and because the polish is excellent, internal reflections are sharp and well defined, creating a three dimensional sparkle that reads as both depth and brilliance to the eye. For a buyer who appreciates technical cutting decisions, the mixed brilliant cut here marries optical performance with the virtue of a classic shape, producing lively brilliance, a pleasing pattern of scintillation, and a broad canvas for the vivid Ceylon blue to show its nuance.

Clarity and treatment are often the most practical considerations for the discerning purchaser, and this sapphire strikes a strong balance between natural character and market expectations. The very very slightly included clarity grade at eye level indicates that inclusions are subtle, they are not intrusive to eye clean appearance in most viewing situations, and they do not materially compromise structural integrity. Under magnification an experienced gemologist may note minute internal features that are useful for identification and origin testing, and such features are also relevant to long term stability and to the gemological narrative that informed buyers value. The stone has undergone heat treatment, a well documented and conventional enhancement for Sri Lankan sapphires that often improves color saturation and removes certain undesirable tones, resulting in a more vivid and homogeneous blue. When properly applied and disclosed, heat treatment is stable and permanent, and it is widely accepted by collectors and the trade as a legitimate enhancement that increases marketability while preserving natural origin and basic identity. Excellent polish further supports the visual impression of clarity by producing smooth facet faces that minimize surface diffusion, and together these attributes make the gem both robust for setting and reliable for long term enjoyment.

For the educated buyer this sapphire represents a compelling convergence of attributes that justify its value, and The Natural Sapphire Company stands behind both the descriptive accuracy and the sourcing provenance. The combination of weight at 3.79 carats, the desirable pear silhouette with dimensions that work elegantly in a variety of mounting styles, the vivid Ceylon blue color, and the clarified clarity assessment all contribute to a gem that can serve as a refined engagement stone, a statement piece for bespoke jewelry, or a collectible for connoisseurs of natural colored stones. Ceylon sapphires are prized for their bright and saturated blues, and provenance from Sri Lanka carries a historical resonance and a quality expectation that informed buyers respect. Practical considerations such as setting recommendations include designs that protect the tapered point and allow sufficient light access to the pavilion to preserve the faceting effect, and metal choices of platinum or 18 karat gold will complement the color depth while providing structural security. Finally The Natural Sapphire Company can assist with independent gemological reporting and documentation where required, and we emphasize responsible sourcing and clear disclosure of enhancements, providing assurance to buyers who prioritize transparency and long term value when acquiring fine natural sapphires.
