0.32 Ct. Green Grandidierite from Madagascar

The Natural Gemstone Company presents a transparent 0.32 carat green grandidierite, precision faceted in an asscher octagon shape with dimensions 4.13 by 4.03 by 2.93 millimeters. The cutting style is faceted, executed as a classical asscher cut with concentric step facets on the crown and pavilion, truncated corners that preserve an octagonal outline, and a calibrated table that balances color and light return. Clarity is graded very very slightly included, evaluated at eye level, and the stone has an excellent polish that minimizes facet windowing and maximizes surface reflection. Origin is Madagascar, and the material has been heat treated to stabilize and intensify the intrinsic green blue tones typical of fine grandidierite. The cutter prioritized depth and pavilion symmetry to retain the stone weight while producing broad facet planes that emphasize color zoning and controlled light leakage, making this piece suitable for precision settings where optical control is required.

Under varied lighting the asscher faceting produces distinct behaviors, because the step facets yield broad flashes and a hall of mirrors effect rather than rapid pinpoint scintillation. In bright daylight the intense color reads as a saturated bluish green, with large, even color fields visible across the table, while secondary pleochroic hues emerge at oblique viewing angles, shifting from a deeper green to a cooler blue green. In direct sunlight the polished facet junctions create high contrast flashes along the step lines, accentuating the asscher geometry, and the slight inclusions remain inconspicuous within the strong color field. Under warm incandescent lighting the stone tends to appear warmer and greener, the step facets softening the contrast and delivering a velvety glow. Under cool white LED or fluorescent light the blue green component becomes more pronounced, and the precise pavilion angles return balanced light, preserving depth rather than washing out the tone. In diffused indoor light the excellent polish and clean facet meet points maintain a steady luster, allowing the eye to appreciate the material texture and internal character. For mounting recommendations, bezel or low profile prong settings will protect the culet while allowing the asscher table and step facets to present maximal color and controlled brilliance, a presentation that reflects the quality standards of The Natural Gemstone Company.
