1.64 Ct. Green Sapphire from Madagascar

This listing describes a single transparent green sapphire, precise weight 1.64 carat, emerald cut shape, with exact dimensions 6.57 x 5.60 x 4.35 mm. The stone displays vivid color intensity, and the clarity has been graded very slightly included, evaluated at eye level. There has been no enhancement to this sapphire. The cut is an emerald style with step facets and defined corners, and the surface finish has been produced to an excellent polish standard. Origin is Madagascar, and the specimen is representative of the notable green sapphire material from that region. The combination of weight, proportions, and clarity yields a gem that reads as a compact and substantial center stone in jewelry applications that prioritize color and presence.

The emerald cut shape emphasizes color saturation through its broad, parallel facets and its open table, while the excellent polish maximizes the smoothness of facet junctions and the evenness of surface reflections. Because the sapphire is transparent with very slight inclusions at the eye level, light transmission through the pavilion is strong, permitting deep color depth without undue cloudiness. The step cut produces larger planes of reflected light rather than the fine scintillation associated with brilliant cuts, so the visual language of the stone is one of broad flashes and color fields. The very slight inclusions are not obtrusive, and they can sometimes contribute subtle internal character when viewed at oblique angles. The combination of the emerald cut geometry, the vivid green hue, and the high quality polish produces a balanced presentation of controlled brilliance, measured contrast, and saturated color.

Under natural daylight the sapphire presents its truest color profile, with the vivid green appearing evenly distributed across the table and through the crown. In open shade and northern daylight the hue takes on a slightly cooler tone, and the broad facets return steady, mirror like flashes that emphasize depth. Direct sunlight increases contrast, producing pronounced flashes along the step facets and momentary sparkle as the stone moves, while simultaneously revealing the richness of the green saturation. Under warm incandescent or warm white LED light the green may read slightly warmer and more luminous, with the stone exhibiting a softer, almost honeyed green glow and a restrained level of sparkle. Cool fluorescent lighting accentuates the pure green aspect of the stone, making the color appear crisper, and the step facets can create a more graphic interplay of light and dark planes. In low ambient light the sapphire retains a strong presence due to its transparency and color saturation, and small highlights will remain visible as focused flashes when illuminated by a point source. When viewed under a spotlight or within a display environment the emerald cut will throw broad, controllable light returns that define each step plane, providing a dignified and architectural optical effect rather than an overall scintillation. In candlelight and other very warm, low intensity environments the stone will present a rich, intimate green, with subdued flash and an emphasis on depth and hue rather than brilliance.

For practical use the measurements and the 1.64 carat weight place this gem in a range suitable for engagement rings, pendants, and bespoke jewelry where a balance between color intensity and wearable size is desired. The emerald cut geometry makes setting considerations straightforward, as the straight lines and defined corners respond well to bezel and prong settings that protect the girdle and corners. The excellent polish reduces the likelihood of surface wear becoming visually distracting, and the corundum family hardness provides strong resistance to everyday abrasion, supporting long term wear with normal care. Origin documentation from Madagascar is available and the lack of enhancement means the stone is presented in its natural state, which is relevant for clients who prioritize untreated material. For cleaning use warm, soapy water and a soft brush, and avoid high heat or harsh chemicals that could affect any mounting materials.
