3.31 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This sapphire presents as a transparent, well proportioned gemstone weighing 3.31 carats, a weight class that materially elevates both market value and rarity for a vivid blue Ceylon material. The gem measures 11.00 x 8.91 x 4.55 mm, dimensions that combine a generous face up area with a comfortable depth for high quality settings. In colored gemstones the incremental increase in carat weight is not linear in value, the presence of a clean, sizeable table and broad pavilion surfaces at this weight typically command a premium per carat due to the relative scarcity of clean rough of this size and color from Ceylon Sri Lanka. This specimen is a significant size for a natural blue sapphire with vivid color intensity, and that weight amplifies its desirability for collectors and for bespoke fine jewelry applications, where scale and presence are as important as tone and saturation.

The gem has been cut as an oval with a mixed brilliant faceting scheme, a deliberate hybrid that marries the scintillation of brilliant faceting to the light performance stability of step like pavilion elements. The crown displays calibrated brilliant facets that promote strong return and scintillation across the table, while the pavilion employs carefully proportioned facets that reduce leakage and minimize windowing, preserving color uniformity when mounted. At the recorded proportions the crown to pavilion relationship supports a lively balance between brilliance and depth of color, while the oval outline has been executed to maintain symmetry and minimize off center table effects. Surface finish is excellent polish across all facet planes, and that level of lapidary finish contributes to crisp facet junctions, sharp light return and clean specular highlights. The girdle appears consistent for secure setting retention, and the facet junctions and polish work together to ensure that the added carat weight reads accurately to the eye, avoiding the apparent loss of spread that can occur in poorly cut heavier stones.

Clarity is graded as eye clean at normal viewing distance, a clarity characteristic that further increases the practical value of this 3.31 carat stone because inclusions that are absent at eye level preserve both visual purity and durability. The vivid color intensity is characteristic of high quality Ceylon sapphires, with a saturated blue that remains lively across different lighting environments due to the combination of hue purity and cut geometry. The stone has undergone heat treatment to optimize tone and saturation, a standard and stable enhancement in sapphire trade practice that improves color homogeneity while retaining natural origin and structural integrity. Origin from Ceylon Sri Lanka is noted for producing stones with vibrant, clean blues that display a particular combination of brightness and velvety saturation, and provenance adds an additional layer of rarity and market preference. For design considerations the stone’s measurements and weight make it ideal for prominent single stone rings, bold pendants, or treasured heirloom pieces, where the 3.31 carat weight will deliver both visual impact and long term market appreciation.

At The Natural Sapphire Company we emphasize exacting standards in selection and presentation, and this specimen exemplifies those criteria through its combination of above average carat weight, transparent clarity at eye level, mixed brilliant faceting and vivid Ceylon color. The weight differentiates this sapphire from more common smaller pieces, because each incremental carat in this weight range represents a proportionally larger fraction of high quality rough that displays the same color and clarity, making this stone both technically superior and comparatively rare. Our lapidary partners have preserved the natural movement of color while maximizing face up spread through careful pavilion planning and precise crown angles, allowing the 3.31 carat weight to contribute directly to optical performance rather than merely adding bulk. For clients who prioritize technical pedigree alongside visual beauty, this sapphire delivers measurable attributes that support its valuation and desirability.
