1.48 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This transparent 1.48 carat oval blue sapphire presents precise dimensions of 7.36 x 4.99 x 4.46 mm, a proportion set that evidences careful weight retention combined with efficient light return. The stone is fashioned in a mixed brilliant cut, employing a brilliant facet arrangement on the crown to maximize scintillation, coupled with a complementary faceted pavilion that contributes balanced return and depth. Clarity is graded as very slightly included when evaluated at eye level, a grade that in practice yields an eye clean appearance while retaining natural internal character that confirms the stone as untreated. The surface finish is described as excellent polish, indicating facet junctions, facet flatness, and girdle execution are held to high standards, resulting in crisp facet reflections and minimal surface abrasion risk. Origin is Ceylon Sri Lanka, a provenance renowned for producing sapphires with lively optical properties, and this piece is confirmed to have no enhancement, offering collectors and connoisseurs a fully natural corundum specimen. The Natural Sapphire Company presents this sapphire as an example of classical materiality combined with contemporary cutting precision.

Color performance in this sapphire is categorized as intense, a classification that references high saturation with an optimal balance of tone to maintain vibrancy without becoming overly dark. The mixed brilliant facet design enhances color by breaking up light into numerous flashes, creating a dynamic interplay between body color and dispersed brilliance. Ceylon origin stones frequently exhibit strong blue chromaticity due to iron and titanium trace elements within the corundum lattice, and this stone expresses that chemistry in a concentrated blue that remains lively across different lighting environments. Optical phenomena relevant to corundum such as dichroism are evident to a trained observer, with the mixed cut facilitating even color distribution by controlling facet angles and table size. The result is a sapphire that reads as intense and saturated when set in jewelry, while still allowing the eye to appreciate internal features that verify natural origin and authenticity.

Durability considerations make this sapphire an excellent candidate for daily wear in jewelry, given corundum s position as one of the hardest gem materials with a Mohs hardness of nine. This hardness confers high resistance to scratching in the context of normal wear, meaning the polished facets will retain luster over time when properly maintained. Toughness in natural sapphire is generally good, and the absence of cleavage in corundum reduces the risk of catastrophic breakage under lateral stress. That said, the very slightly included clarity grade advises standard precautions, such as avoiding sustained blunt impacts that could exploit localized internal stress points. The excellent polish contributes to prolonged surface resilience, since a high quality polish minimizes microabrasion that otherwise weakens facet edges. For settings intended for daily wear, secure prong systems with at least four well-formed prongs, or a low profile bezel mount that protects the girdle and crown, are recommended. Periodic inspection of the setting is advised to ensure prongs remain tight, and routine cleaning with warm soapy water and a soft brush will preserve brilliance, while avoidance of harsh chemicals and extreme thermal shocks will guard the stone s integrity.

From a design and craftsmanship perspective, this oval sapphire s dimensions and mixed brilliant cut make it versatile for a variety of jewelry applications, including ring centers, pendant focal points, and matched earrings where identical calibrations are possible. The length to width ratio implicit in the supplied measurements produces an elegant oval silhouette that elongates the finger when used in rings, while the depth retained by the pavilion preserves weight and visual presence without compromising light behavior. The mixed brilliant strategy optimizes both dispersion and overall brilliance, so the gem exhibits lively scintillation in motion, combined with a steady body color at rest. Because the stone is unheated and unenhanced, it carries intrinsic value for specialists who prioritize untreated material, and its Ceylon origin is a further credential for those familiar with regional character in sapphires. If you require detailed facet maps, mounting recommendations, or comparison to other stones of similar weight and cut, The Natural Sapphire Company can provide lapidary schematics and setting mock ups to assist in final design decisions, ensuring the technical specifications of the gem are matched to an appropriate jewelry architecture for reliable, long term daily wear.
