3.69 Ct. Yellow Sapphire from Ceylon (Sri Lanka)

This listing describes a single transparent yellow sapphire weighing 3.69 carats, presented by The Natural Sapphire Company, originating from Ceylon, Sri Lanka. The stone measures 9.65 x 7.21 x 5.19 mm, and is fashioned in a classic emerald cut. The color is described as medium intensity, offering a clear, lively yellow that is consistent across the table and through the crown. The clarity grade is very very slightly included when evaluated at eye level, indicating that inclusions are minimal and do not materially affect the visual performance of the stone. The finish is of excellent polish, and the material has been heat treated, a standard and stable enhancement in the trade to optimize color and clarity, disclosed and documented by our quality control procedures.

The emerald cut itself plays a central role in the way this sapphire communicates light, and the geometry of the step facets has been selected to enhance both the tone and the internal reflection characteristics of the material. Wide, linear step facets on the crown and pavilion create parallel planes that reflect light back toward the viewer in broad, even flashes, rather than in a spray of small scintillation. This facet arrangement emphasizes the stone s natural transparency and color, producing a hall of mirrors effect that increases perceived depth and richness. The elongated rectangular table allows for a generous window into the body of the sapphire, while the stepped pavilion facets guide light in a controlled manner to reduce unwanted light leakage, preserving face up color and delivering measured brilliance. The emerald cut s architectural symmetry also serves to harmonize the distribution of color, making the medium intensity yellow appear uniform and balanced under a range of lighting conditions.

Clarity and polish are critical partners to the cut when it comes to optical performance, and this sapphire s very very slightly included clarity grade at eye level means that the internal features are minor, isolated, and do not interrupt the path of light in any significant way. Under normal viewing, the stone presents as clean, allowing uninterrupted light travel through the pavilion and back through the table, which optimizes both brightness and color saturation. The excellent polish enhances surface reflectivity, creating crisp facet junctions that contribute to clean reflections and well defined facet contrast. The heat treatment applied to this material has been performed to gently intensify hue and to stabilize the bodycolor, which in turn complements the emerald cut by producing a steady and appealing yellow without localized zones of overly dark or pale tone. The combination of origin, treatment, clarity, and cutting style results in a sapphire that balances sparkle with broad, luminous flashes, delivering a refined and controlled light performance.

From a practical perspective the stone s dimensions of 9.65 x 7.21 x 5.19 mm and its weight of 3.69 carats place it in a versatile size range for a variety of settings, including solitaire rings, three stone compositions, or as the focal point in bespoke designs. The well proportioned depth, approximately sixty two percent in relation to the length and width, supports secure setting options while maintaining optimal face up presentation. As with all corundum, the sapphire is durable enough for everyday wear, offering long term resilience to abrasion and the demands of regular use. The Natural Sapphire Company documents the origin and enhancement status of this gem, and our team is available to provide additional imagery, plotting, or advice on mounting choices to preserve the stone s visual characteristics. This description is intended to convey the technical and aesthetic qualities of the sapphire in clear terms, enabling informed decisions about design and setting, while acknowledging the craftsmanship inherent in the emerald cut that so effectively reveals the stone s inherent light handling properties.
