2.23 Ct. Greenish Blue Sapphire from Madagascar

This specimen is a transparent greenish blue sapphire, 2.23 carats, cut in a classic emerald shape, with dimensions 8.90 by 5.90 by 4.04 millimeters. Its measured proportions and weight reflect careful rough planning to maximize color saturation and maintain an even pavilion depth. Color assessment records a vivid intensity, and clarity has been graded as very slightly included when evaluated at eye level, indicating minimal internal features that do not compromise transparency. The stone is unenhanced, and provenance is Madagascar, a source known for producing sapphires with strong natural color and stable crystal structure. The Natural Sapphire Company presents this stone as a natural, untreated example of high quality material that combines desirable size and vivid hue with excellent polish and faceting precision.

The emerald cut on this sapphire has been executed with technical restraint to emphasize broad step facets and linear light return. The cut shows a length to width ratio of approximately 1.51, which creates an elongated rectangular profile well suited to both solitaire and halo settings. Facet geometry follows a stepped crown and pavilion arrangement, producing broad, clean flashes rather than scattered scintillation, and enabling the rich greenish blue hue to read evenly across the table. The overall depth is approximately 54.6 percent when calculated against the average of length and width, a proportion that balances internal reflection with face up color saturation. Symmetry and girdle consistency are precise, and the excellent polish minimizes surface diffusion of light, preserving crisp facet junctions that contribute to the gem behaving like a miniature architectural plane of color.

Color and clarity performance work together in this sapphire to produce optical depth and nuance. The vivid color intensity indicates a robust combination of tone and saturation that allows the greenish blue hue to remain lively under a range of lighting conditions, from natural daylight to warm indoor illumination. Step cutting in this form brings out broad color zones and can reveal subtle pleochroic effects in corundum, and here the result is a stable, deep face up color with lively internal reflections along the longer table. Clarity graded as very slightly included at eye level means that inclusions are minor, small in size, and positioned in locations that do not interrupt the primary light paths through the pavilion. This translates to a gem that appears highly transparent to the unaided eye and that retains strong brilliance and color saturation. Because the stone is untreated, the color and clarity characteristics are wholly natural, offering collectors and connoisseurs confidence in the material integrity.

From a setting and design perspective the craftsmanship of the cut and the finish are what allow this stone to exhibit beauty from every angle. The excellent polish delivers mirror like facet planes that throw clean reflections, enhancing the perception of depth and the clarity of color across the table and step facets. Precision facet alignment ensures that when the stone is tilted or rotated the color transitions are gradual and controlled rather than patchy or zoned, a quality particularly valued in step cut stones for bespoke jewelry. Practical considerations include a stable girdle for secure mounting, and the elongated emerald silhouette allows for a range of design choices, from classic four prong settings that showcase the table to bezel mounts that emphasize the stone cosmetically and protectively. The Natural Sapphire Company recommends evaluating the stone under both daylight and standard jewelers lighting to appreciate its full optical behavior, and our team can provide additional imaging and certified documentation for customers who require formal verification of origin and condition.
