3.60 Ct. Bluish Green Sapphire from Madagascar

This transparent bluish green oval sapphire weighs 3.60 carats, a significant weight that elevates both its rarity and market value for a stone with intense color and eye clean clarity. The gem measures 10.19 by 8.16 by 5.06 millimeters, yielding an approximate length to width ratio of 1.25 to 1 and an overall depth of about 55 percent, proportions that balance face up area with optimal light return. Cut in a faceted mixed brilliant style, the crown employs a precise arrangement of brilliant facets to maximize scintillation, while the pavilion facets are calibrated for controlled internal reflection and strong return of blue green tones. The mixed brilliant design preserves weight while delivering lively brilliance, and the excellent polish and careful symmetry enhance table and facet junction precision, reducing light leakage and accentuating the stone s intense saturation.

Evaluated as eye clean at standard viewing distances, this Madagascar sapphire displays a pure transmission with minimal inclusions visible only under magnification, a clarity level that contributes materially to its premium pricing at this weight class. The intense color intensity, complemented by subtle pleochroic behavior that alternates between blue and green flashes depending on orientation, is characteristic of trace element chemistry from Madagascar sources, and the stone has been heat treated to stabilize and enrich its hue, a widely accepted enhancement that preserves natural integrity while improving market appeal. At 3.60 carats, the value curve is exponential rather than linear, making this sapphire notably rarer than smaller counterparts, especially when combined with excellent polish, mixed brilliant faceting, and transparent body color. The Natural Sapphire Company presents this gem as an example of superior craftsmanship and gemological quality, ideal for connoisseurs seeking a substantial, collector grade sapphire where weight, cut precision, color intensity, and origin converge to produce an exceptionally desirable gemstone.
