Translucent Midnight Blue Cornflower Sapphire 3.84 CT Oval Cut from Mozambique
This 3.84 ct oval sapphire from northern Mozambique presents a classic cornflower blue medium tone with a velvety, twilight undertone that stays luminous in all light. Translucent with fine silk and cloud like veils, it diffuses light into a graceful inner glow while crisp crown facets provide confident sparkle. The oval is well-proportioned and elegantly spread, giving commanding presence without excess depth an exceptional size for a refined heirloom centerpiece.
Species: natural sapphire, corundum (Al₂O₃); Mohs hardness 9 for outstanding durability; uniaxial negative with pleochroism from cornflower to violet-blue; RI ~1.760–1.770; SG ~4.00. Origin: Mozambique, from the alluvial fields of the Niassa Cabo Delgado region, known for richly saturated blues.
