0.72 Ct. Bluish Green Sapphire from Madagascar

This bluish green oval sapphire is a refined example of natural corundum, weighing 0.72 carat and measuring 6.48 by 4.84 by 2.78 millimeters. Cut into an elegant oval with a mixed brilliant facet arrangement, the stone combines a brilliant crown to maximize scintillation with a faceted pavilion designed to retain weight and depth of color. At this scale the mixed brilliant approach is particularly effective because it concentrates light return across the table and along the long axis of the oval, creating lively flash without sacrificing the saturation that gives the stone its intense color intensity. The clarity has been assessed as very very slightly included at eye level, which for an educated buyer means the gem is essentially eye clean, with only minute internal characteristics detectable on close inspection and typically visible only under magnification. The polish is described as excellent, indicating sharp facet junctions and minimal surface abrasions, and crucially, this sapphire is untreated, no enhancement, which materially increases its rarity and market value when compared with heat treated stones that dominate the trade.

The origin of this sapphire, Madagascar, is important context for both connoisseurs and collectors. Madagascar is one of the world’s most significant sapphire sources since the late 20th century, producing a broad spectrum of hues from classic cornflower blue to the rarer bluish green and teal tones. Historically, sapphires have been prized across civilizations for their perceived protective and ceremonial properties, from ancient Near Eastern priestly rings to royal and ecclesiastical jewels in medieval Europe where blue corundum symbolized heaven and fidelity. Green and bluish green shades, while less traditional than pure blue, were often used historically as talismanic stones and in settings where verdant tones were associated with renewal and balance. This particular stone carries that lineage forward, offering a modern collector a gem that resonates with those traditional uses, while also representing the new era of Malagasy production, where responsible sourcing and traceability are increasingly emphasized. For buyers who appreciate provenance, knowing this sapphire’s origin in Madagascar adds a layer of narrative and geological interest that complements its physical attributes.

From a practical and investment perspective the combination of eye clean clarity, intense color intensity, excellent polish, and lack of enhancement establishes this sapphire as a gemstone of lasting value. Corundum’s hardness, ranking nine on the Mohs scale, ensures outstanding durability for everyday jewelry such as engagement rings, signet rings, or pendants, and the oval silhouette with mixed brilliant cut adapts beautifully to classic solitaire settings, halo designs that amplify perceived size, or custom vintage inspired mounts that highlight the stone’s subtle greenish blue hue. For color considerations, the bluish green tone pairs exceptionally well with both white metals and warmer yellow or rose gold, where the contrast can emphasize either the cooler blue facets or the greener undertones. At The Natural Sapphire Company we place a premium on accurate grading and transparent disclosure, and this sapphire’s combination of natural origin, untreated status, and meticulous cutting make it particularly appealing to the educated buyer who seeks both aesthetic appeal and provenance. Care recommendations are straightforward, given corundum’s durability, but gentle ultrasonic cleaning in appropriate solutions or routine warm soapy water with a soft brush will maintain brilliance without risk. This stone is an excellent choice for someone seeking a gem that balances historical significance, geological provenance, and technical quality, and it represents the kind of responsibly sourced, characterful sapphire that discerning collectors and jewelry designers prize.
