0.48 Ct. Yellowish Orange Sapphire from Ceylon (Sri Lanka)

This transparent 0.48 carat oval yellowish orange sapphire presents a balanced combination of precise dimensions and refined workmanship, measured at 5.08 x 3.96 x 2.68 millimeters. The stone is fashioned in an oval outline with a mixed brilliant cut, designed to maximize light return while preserving a clean, classic silhouette for mounting. Clarity has been evaluated at very slightly included at eye level, indicating minor internal characteristics that do not detract from face up brilliance or overall appeal. The color shows a vivid intensity, a lively yellowish orange that reads consistently across different viewing angles, and the polish has been graded excellent, yielding crisp facet junctions and a smooth reflective surface. This sapphire is from Ceylon Sri Lanka, a source well known for its range of warm and saturated tones, and the piece has undergone intentional beryllium diffusion enhancement to achieve and stabilize its vivid color. The Natural Sapphire Company presents this gem with full disclosure of its origin and treatment, and the technical specifications reflect both its aesthetic qualities and its suitability for fine jewelry applications.

Internal characteristics within natural sapphires serve as intrinsic markers of provenance and formation, and in this instance the inclusions should be considered distinguishing features that add to the gem's character. When examined closely, such features may include minute mineral crystals, subtle growth zoning, and tiny channels or fluid inclusions that record the sapphire's geological history. These internal traits are often invisible to the unaided eye in sapphires graded as very slightly included, yet they remain useful to gemologists and experienced cutters for identification and verification. In practical terms, these characteristics do not compromise structural integrity, and they contribute to the stone's individuality in a manner analogous to a fingerprint. For clients seeking a stone with both natural origin and a distinctive appearance, the presence of these internal markers offers reassurance of authenticity and provides a narrative element that enhances the gem beyond mere measurements.

The mixed brilliant cut employed on this oval sapphire performs two complementary functions, enhancing scintillation while preserving depth of color. The pavilion and crown facet arrangement creates lively return of light, which emphasizes the vivid yellowish orange tone without producing excessive dark areas or windowing. Because the stone has been beryllium diffused, the intensified color is the result of a diffusion process that alters trace element distribution to produce stable, saturated hues. Beryllium diffusion is considered a permanent treatment under normal conditions of wear, and it is widely accepted within the trade when fully disclosed. From a practical standpoint, this sapphire benefits from the inherent hardness and toughness of corundum, making it suitable for everyday jewelry if set appropriately. For ring applications, protective settings such as bezel or half bezel mounts help safeguard the girdle and edges, while pendant and earring settings can showcase the color and cut with minimal risk of impact. The modest dimensions and weight make this gem particularly well suited to designs that prioritize color and refined proportions over large size.

The Natural Sapphire Company offers this Ceylon yellowish orange sapphire with guidance on certification, mounting options, and care recommendations to support responsible ownership. We recommend routine cleaning with warm water, mild detergent, and a soft brush, avoiding strong chemicals and prolonged exposure to high heat, which can affect mounted settings and ancillary materials. Professional inspection of the setting and periodic rechecking of mounting prongs will preserve both aesthetic and secure wear. For clients seeking documentation, we provide detailed measurement and treatment disclosure supporting transparent provenance, and we can assist with bespoke design services to integrate this sapphire into a tailored piece. In summary, this 0.48 carat oval mixed brilliant sapphire combines transparent clarity with vivid yellowish orange color, a very slightly included clarity grade as viewed at eye level, and excellent polish, together with the distinctive story of Ceylon origin and beryllium diffusion enhancement, offering a gem that is both technically well described and authentically individual.
