0.59 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This transparent 0.59 carat oval blue sapphire presents precise proportions at 5.73 by 4.12 by 2.74 mm, rendered in a mixed brilliant cut that balances scintillation with color depth. The cutting style pairs a brilliant facet schema on the crown with a carefully proportioned step pavilion, generating lively return of light across the table and controlled dispersion through the pavilion, the result is a gem that reads both lively and deep at varied viewing angles. Clarity is graded very slightly included when evaluated at eye level, the inclusions are minor and do not distract from the overall brilliance, they are consistent with natural corundum and confirm the stone is not heavily modified beyond standard enhancement. Color intensity is dark, the face up hue is a saturated blue with subtle greenish overtones that accentuate depth under direct light, and excellent polish enhances facet junction crispness and overall visual appeal. The gem is heat treated, a stable and accepted enhancement for Ceylon sapphires, used to refine tone and saturation without altering the gemological identity, and origin is Ceylon, Sri Lanka, a source known for well colored, transparent material and traditional lapidary expertise.

From a design and wearability perspective this sapphire is exceptionally versatile, suitable for both elevated everyday jewelry and formal occasion pieces, its compact oval outline and mixed brilliant faceting lending itself well to single stone rings, delicate pendants, and refined stud or drop earring settings. The moderate table and measured pavilion depth allow the stone to sit attractively in bezel, half bezel, and claw mounting styles, maintaining face up color while offering secure setting options for daily wear. For clients seeking a statement in a compact weight class, the stone translates into a strong presence in three stone and halo compositions, while remaining understated when set as a solitary accent.
