1.60 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This GIA certified natural blue sapphire is a refined example of Ceylon gemology, weighing 1.60 carats and cut into a classic cushion shape with dimensions of 8.13 by 5.92 by 3.41 millimeters, mixed brilliant faceting, and a transparent body. The GIA report provides independent verification of weight, measurements, and the unenhanced origin of this stone, giving you objective assurance of authenticity. The clarity grade is eye clean when evaluated at normal viewing distance, which means that despite the presence of internal features, the stone presents a clean, uninterrupted face up appearance to the unaided eye. Color intensity is described as intense, and the polish is excellent, both attributes that contribute directly to the visual impact and longevity of the gem. The combination of these technical details defines the gem as a collector quality sapphire, suitable for fine jewelry and long term holding.

The rich, intense blue of this Ceylon sapphire is the single most important determinant of its value to a discerning buyer, and this stone exhibits the saturated yet lively tone that Sri Lankan deposits are celebrated for. Ceylon sapphires can range from soft cornflower blue to vivid velvety blue, and this gem sits comfortably in the more saturated and desirable part of that spectrum. Because this sapphire has not been subjected to heat or other enhancements, the color is entirely natural, which is increasingly rare and coveted in the market. For an educated buyer, the absence of enhancement carries a price premium because it preserves the stone in its natural state and allows the market to distinguish it as an authentic specimen from an historic gem producing region. The GIA certificate serves to document these claims, which is important both for resale valuation and for insuring provenance.

The mixed brilliant cushion cut is chosen to balance strong face up presence with scintillation and light return, converting the stone dimensions into a lively, wearable size. The mixed brilliant arrangement combines a larger pavilion facet architecture with a carefully proportioned crown, which maximizes brilliance while preserving depth of color. The dimensions of this stone yield a pleasing table to depth relationship, allowing the intense blue to show without appearing overly dark or windowed. Excellent polish ensures that light passes into and out of the gem with minimal surface diffusion, producing crisp reflections and boosting perceived clarity. For designers and connoisseurs who value precision cutting, this sapphire provides an ideal platform for either a solitaire setting that emphasizes color, or a halo configuration that adds perceived size while highlighting the gem center.

What gives this sapphire an unmistakable signature is the specific pattern and nature of its internal inclusions, features that speak to the stone origin and history while remaining unobtrusive to the eye. The stone exhibits a fine network of silk like rutile needles that are natural to many Sri Lankan sapphires, configured in delicate, intersecting bundles that subtly soften and distribute the blue, producing a velvety lustre from within. Alongside those needles are minute crystal inclusions and occasional tiny negative crystals or healed fissures, which together form an internal map unique to this gem. These inclusions are diagnostically important, because their morphology and distribution are consistent with natural formation and absence of heat treatment, and they create a fingerprint that can be used for identification by a gemologist equipped with photographic mapping. Importantly, the arrangement of these features is such that they do not compromise the structural integrity or face up transparency of the stone, giving the wearer the best of both worlds, natural character and visual purity.

For an informed purchaser evaluating long term value, this sapphire from The Natural Sapphire Company represents a convergence of verified origin, natural intense color, clean eye level clarity, and cut quality that optimizes appearance. Unheated Ceylon sapphires of this weight and color are relatively scarce, and the GIA certification further supports market confidence and insurability. From a practical perspective the gem adapts well to many design approaches, including a classic four prong or low profile bezel for everyday wear, or a more elaborate halo with accent diamonds to enhance face up size while maintaining focus on the blue. We recommend professional setting to preserve the stone and to optimize light performance.
