0.85 Ct. Greenish Blue Sapphire from Madagascar

This 0.85 carat oval greenish blue sapphire presents exacting proportions and a disciplined faceting scheme that will appeal to connoisseurs and designers alike. Measured at 5.94 by 5.42 by 3.20 millimeters, the stone exhibits an overall depth of approximately 56 percent, a proportion that balances color saturation with optimal light return for a small oval. The mixed brilliant cut features a brilliant style crown paired with a faceted pavilion that integrates step influenced facets, a combination that deliberately maximizes scintillation while preserving depth of hue. Facet junctions have been executed with care, contributing to an excellent polish that produces crisp facet reflections and minimizes diffusion of light across the crown. The oval outline is slightly elongated without exaggerated length, enabling clean symmetry and predictable behavior when set, whether in a bezel, prong, or halo mounting.

Color performance is the defining attribute of this sapphire, recorded as intense in color intensity and described as greenish blue in tone. The hue occupies a refined position between true blue and teal, delivering a lively and complex appearance that shifts subtly with angle and lighting conditions. Pleochroic effects typical of corundum are present, producing faint variations between blue and green components as the stone rotates, which enhances perceived movement and depth. The mixed brilliant topology enhances color vibrancy by creating high contrast flashes against saturated windows, so the gem reads as more vivid in direct light and more velvety in diffuse illumination. Heat treatment has been applied, a stable and industry standard enhancement that refines zoning and strengthens the uniformity of the intense hue without compromising the stone’s natural character. Origin from Madagascar is noted, a locality known for producing sapphires with lively secondary tones and pleasing saturation, and this specimen exemplifies that provenance in its layered color complexity.

Clarity is graded as very very slightly included, evaluated at eye level, indicating that any internal features are minute and do not detract from the gem’s overall transparency or visual performance to the unaided eye. The combination of VVS clarity and excellent polish allows light to traverse the pavilion and return through the crown with minimal interruption, so brilliance and fire remain prominent despite the stone’s deeper color. As corundum, the sapphire offers exceptional durability with a Mohs hardness of nine and refractive indices in the range expected for natural sapphire, characteristics that make it suitable for everyday wear in rings, pendants, and other frequently handled jewelry. When mounted in yellow gold, the greenish component becomes more pronounced, creating a warm contrast that reads as teal, while platinum or white gold emphasizes the pure blue aspect for a cooler, more classical presentation. The Natural Sapphire Company presents this gem as a technically refined yet naturally expressive option for commissions and ready settings, a stone that will reliably stand out within any jewelry design due to its intense color, precision cutting, and polished finish.
