3.13 Ct. Purple Sapphire from Ceylon (Sri Lanka)

This sapphire is a precisely measured 3.13 carat oval, with dimensions of 9.88 by 7.50 by 5.25 millimeters, presenting a length to width ratio of approximately 1.32, and an overall depth that measures at roughly 60.4 percent of the average diameter. The oval outline is clean and symmetrical, offering balanced faceting planes and a refined silhouette that reads well in a wide range of settings. The mixed brilliant cut employed combines a carefully calibrated brilliant facet pattern on the crown with a complementary pavilion design that optimizes both return of light and colour saturation. The table and crown proportions have been managed to retain transparency and to prevent washout of the intense purple bodycolour, while the pavilion geometry contributes to uniform light distribution across the stone. Weight distribution is efficient, making the 3.13 carat mass present with a substantial face up size given the profile dimensions, and the excellent polish ensures uninterrupted transfer of light from crown to viewer.

The mixed brilliant faceting on this stone is intentionally executed to take advantage of sapphire optical properties, using a multi facet brilliant crown to generate scintillation and lively dispersion, and a pavilion scheme that deepens and stabilizes hue. This approach leverages both brilliant style and step influenced elements, producing crisp flashes when the stone is moved, together with colour zoning that reads evenly across the table. Facet junctions are well aligned and symmetry is maintained along the major and minor axes of the oval, which reduces leakage and supports strong return through the table. The cut also moderates windowing, allowing the intense purple to remain saturated without becoming overly dark at the edges. Excellent polish on all facets enhances luster and allows sharp facet reflections, which is particularly important with a high intensity colour stone, because polished facet faces maximize perceived depth and deliver the tactile sense of quality that experienced buyers expect.

Clarity is graded as very slightly included, evaluated at eye level, a designation that indicates inclusions are minimal and do not materially impede transparency or brilliance in normal observation. In practical terms the stone presents as transparent and clean to the unaided eye, with the minor internal features contributing to natural character rather than detracting from optical performance. This level of clarity is consistent with fine natural sapphires and supports both optical purity and durability when set. Colour intensity is classified as intense, and the saturation reads as strong and even across the crown and pavilion, providing a vivid purple appearance that remains lively under variable lighting. The origin is Ceylon Sri Lanka, a source noted for producing sapphires with lively tones and attractive vibrancy, and this piece is offered without enhancement. The absence of heat treatment or other enhancement is significant from a gemological and market perspective, because untreated Ceylon material with intense colour is comparatively rare and highly sought after by collectors and connoisseurs.

Owning this purple sapphire is an investment in both aesthetic and technical quality, and The Natural Sapphire Company presents it as an example of considered craftsmanship and ethical sourcing. From a collector standpoint the combination of untreated origin, intense colour, controlled proportions, and superior polish creates a stone that is likely to retain desirability over time. From a jewellery design perspective the oval 3.13 carat format is versatile, lending itself to classic solitaire rings with protective bezel or prong cages, to three stone settings that emphasize length and symmetry, and to bespoke pendant designs that showcase colour concentration and movement. The mixed brilliant cut preserves brilliance while maximizing colour, which means the stone will perform well under both diffuse and directional light, maintaining eye appeal in daily wear. Acquisition through The Natural Sapphire Company also denotes access to expertise in setting recommendations and conservation advice, ensuring that the stone is mounted in a way that protects its proportions and surface finish, and that the long term presentation remains true to the gemologists assessment. This sapphire is therefore an investment in beauty, in technical excellence, and in the provenance that distinguishes untreated Ceylon pieces in the marketplace.
