1.39 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This pear shaped blue sapphire weighs 1.39 carats and measures 8.67 x 5.25 x 4.10 mm, producing a length to width ratio of approximately 1.65 which yields a classic elongated pear silhouette. The gem is cut in a mixed brilliant style, combining a brilliant faceted crown that maximizes scintillation with a pavilion geometry tuned for controlled light return, producing a focused light performance and lively face up brilliance. Clarity is graded slightly included at eye level, indicating the presence of minor internal features that do not materially impede transparency or light performance, and which contribute to the natural character of the stone. Color is described as intense, a saturated Ceylon tonality that balances deep blue saturation with a lively medium to slightly deep tone, and the stone presents transparent body color with consistent saturation across the table and shoulders. The polish is excellent, the facet junctions are well defined, and the overall symmetry supports strong optical performance. Enhancement has been performed by heat treatment, a stable and conventional treatment for corundum, and origin is Ceylon, Sri Lanka, noted for producing sapphires with vivid blue hues and brisk internal lustre.

For an heirloom quality piece the technical attributes of this sapphire are particularly well suited to longevity and versatility. Corundum rates nine on the Mohs scale, providing exceptional resistance to abrasion for daily wear, and the mixed brilliant cut with excellent polish reduces the need for reworking that can diminish weight and alter proportions over generations. The 1.39 carat weight and balanced pear proportions make the gem ideal for a protective setting, such as a bezel or a reinforced V prong at the tip, which preserves the apex while allowing the crown facets to contribute maximum brilliance in rings, pendants, or brooches. The documented Ceylon origin and disclosed heat treatment are part of the provenance that collectors and families value, and The Natural Sapphire Company provides certification and condition records that can travel with the stone through successive owners. Routine care with warm, soapy water and a soft brush, and periodic inspection of the setting by a qualified jeweller, will maintain the finish and stability of the stone. With its robust material properties, considered cut, and verifiable provenance, this sapphire is technically and aesthetically equipped to become a treasured generational heirloom.
