15.98 Ct. White Sapphire from Ceylon (Sri Lanka)

This exceptional transparent white sapphire is GIA certified, presenting as Near Colorless and weighing 15.98 carats, with dimensions 15.02 by 14.82 by 10.22 millimeters. The round shape is executed as a mixed brilliant cut, combining a faceted brilliant style crown with a modified pavilion geometry to optimize return of light and scintillation. The average diameter of this stone is approximately 14.92 millimeters, producing a depth proportion of about 68.5 percent, a geometry that delivers pronounced crown presence and a deep pavilion for concentrated white light return. Clarity is graded as very slightly included at eye level, with the inclusions being minor and well situated so as not to interfere with the gem s overall transparency or the crispness of facet junctions. The polish has been assessed as excellent, yielding sharply defined facet planes and minimal surface abrasion, which together enhance both brilliance and the calm white sparkle characteristic of fine white sapphires.

From a cutting and faceting perspective, the mixed brilliant offers the best of both worlds, balancing bold, lively scintillation with controlled light leakage and a pleasing star pattern when viewed face up. The crown displays precisely proportioned triangular and kite facets, converging to a well centered table which frames the internal brilliance, while the pavilion facets are carefully angled to promote efficient internal reflection. These facet relationships are responsible for the strong white flash and the steady play of light seen across the face of the gem, attributes that are important for a piece intended as a focal point in fine jewelry. The excellent symmetry and even facet distribution confirm a high level of lapidary skill, and the lack of enhancement assures that this optical performance is entirely natural, with no heat treatment or diffusion applied to alter color or clarity.

Origin is Ceylon Sri Lanka, a provenance known for producing sapphires with exemplary crystal clarity and clean color profiles, and the GIA report provides independent verification of both the near colorless grade and the fact that no enhancements are present. The combination of a large 15.98 carat weight and natural, untreated origin places this stone in a rare category, making it an outstanding choice for collectors and connoisseurs who prioritize natural gemology. The girdle bears an inscription consistent with inventory tracking, confirming traceability and provenance for purchasers, and The Natural Sapphire Company stands behind the gem with full documentation, detailed imaging, and the option for consultation regarding setting recommendations to maximize optical performance.

For gifting, this sapphire makes a striking, memorable present for someone special, owing to its size, clarity, and natural, unenhanced character. As a center stone, it will assert presence whether set in a classic solitaire ring, a high gallery pendant, or an important heirloom brooch, and its mixed brilliant cut will ensure it reads as luminous and alive under a wide range of lighting conditions. The technical virtues of the gem, including the deep pavilion, excellent polish, and very slightly included clarity at eye level, translate directly into a visual statement that feels both modern and timeless. When presented by The Natural Sapphire Company, this GIA certified Ceylon white sapphire becomes more than a gemstone, it becomes a singular expression of craftsmanship and provenance, an exceptional gift that will be treasured for generations.
