1.02 Ct. Yellow Sapphire from Ceylon (Sri Lanka)

This transparent 1.02 carat oval yellow sapphire from Ceylon Sri Lanka presents precise proportions and artisanal finish, making it ideal for high quality bespoke jewelry. The gem measures 7.42 by 5.34 by 3.22 mm, and it has been cut to a mixed brilliant facet arrangement, combining a brilliant crown with a modified pavilion to optimize scintillation while preserving strong face up color. Color intensity reads as intense, and the tone sits in a pleasing mid to lively range that reads as a vivid lemon to golden yellow depending on light. Clarity is graded as very slightly included when evaluated at eye level, with internal features that are minor and well distributed so as not to interrupt the overall light performance. The polish is excellent, producing crisp facet junctions and clean facet planes that enhance both brilliance and luster. There has been no enhancement to the stone, delivering a wholly natural color and clarity profile that is consistent with responsibly sourced Ceylon material, and the piece is presented and described by The Natural Sapphire Company.

The mixed brilliant cut employed for this oval sapphire is deliberately balanced to achieve both color saturation and dynamic light return, using a relatively broad table to allow clear face up presence, combined with a series of well calibrated crown facets to generate flashes of white light. The pavilion has been faceted to control depth and to reduce windowing, which is particularly important for yellow tones that can appear washed when pavilion angles are too shallow. The girdle is proportionate and even, and the culet is retained at a size that avoids light leakage without introducing a visible dark spot under typical viewing conditions. Observed inclusions are small and predominantly internal, with no feathering or surface reaching fissures that would compromise durability. For precision jewelers and gem designers, these facet relationships translate into predictable optical behavior and reliable compatibility with a range of mounting types.

Customization possibilities for this 1.02 carat oval yellow sapphire are extensive, and the gem is particularly well suited to both classic and contemporary treatments. In a solitaire prong ring the oval long axis can be set either north south for a traditional look, or east west for a modern profile, with four or six low profile prongs securing the stone while preserving maximum light entry. A bezel setting will provide superior protection and a clean graphic outline, and can be executed as full bezel for apportioning visual mass, or as a thin rim to maintain brightness, with internal seat milling matched to the measured pavilion depth of 3.22 mm. A halo design using small brilliant cut accent stones can increase perceived diameter and enhance scintillation, and when calibrated correctly the halo can also serve to mask minor inclusions when viewed face up. Three stone and side stone arrangements allow pairing with tapered baguettes or shield cuts, and cluster layouts can be engineered to create vintage inspired silhouettes while maintaining structural integrity. For pendant applications the stone is well suited to low profile bezels and articulated bails, and for stud earrings paired with a matching sapphire or diamond accents the measured dimensions yield comfortable proportions for both day wear and evening use. Tension settings require precise diameter and crown clearance, and while technically feasible they demand exact seat engineering to preserve the gem without introducing stress points.

Material selection, mounting engineering, and complementary stones will determine the final aesthetic and optical effect, and several configurations are particularly recommended for this yellow sapphire. Warm yellow gold will harmonize with the inherent color, producing a rich continuous appearance, while rose gold will add a soft warm contrast that emphasizes golden undertones. Platinum and white gold will produce a cooler white metal contrast that makes the yellow read brighter and more lemon in tone, which can be desirable when a crisper color separation is intended. Pairing options include high color index white diamonds to increase scintillation, cognac diamonds to accentuate warmth, and green emerald or teal tourmaline accents for a high contrast contemporary palette. From a craftsmanship perspective, hand finishing techniques such as low profile millimeter exact bezel seats, hand engraved shoulders, and fine milgrain can be applied to framing the stone without obscuring optical access. The Natural Sapphire Company offers CAD visualization, handcrafted mounting, and precision setting services, enabling exact replication of design intent and ensuring that the mounting tolerances match the 7.42 by 5.34 by 3.22 mm dimensions and the pavilion depth so that the finished piece retains maximum brilliance, secure setting, and longevity. For clients and trade jewelers who prioritize untreated provenance and balanced optical performance, this oval yellow sapphire represents a highly adaptable center stone for rings, pendants, earrings, and bespoke multi stone compositions, and our team can provide technical drawings, mounting recommendations, and setting options to meet both aesthetic goals and engineering requirements.
