0.58 Ct. Alexandrite from Madagascar

This 0.58 carat cushion shape alexandrite presents a remarkable balance of proportions and optical performance, with precise dimensions of 5.39 by 3.77 by 3.15 millimeters. Cut as a mixed brilliant, the stone combines a brilliant crown with a carefully executed step influenced pavilion, optimizing both scintillation and color saturation. The faceting strategy emphasizes a moderately sized table and slightly deeper pavilion depth to enhance the inherent dichroism of alexandrite, allowing the bluish green face up color to transition decisively to a reddish purple in incandescent lighting. Color intensity is graded as intense, and the stone exhibits clean, vivid hue separation across light sources, with pleochroic zones that respond predictably to facet orientation. Clarity is graded as very slightly included when evaluated at eye level, with inclusions that are minimal and well positioned so as not to interrupt light return or overall visual appeal. The polish has been executed to an excellent standard, yielding crisp facet junctions and smooth facet planes that maximize luster and minimize surface diffusion. There has been no enhancement applied to this gem, preserving its natural material properties and spectral characteristics. The origin is Madagascar, an increasingly important source for fine alexandrite material, and this provenance contributes to the stone's appeal for collectors and connoisseurs.

From the mine to market, the journey of this alexandrite was governed by technical discipline at every stage, starting with targeted extraction in Madagascar where rough pieces were evaluated for color change potential and material stability. The selected rough underwent digital mapping and optical modeling to determine ideal orientation for the cut, prioritizing directions where pleochroism and color change are strongest. Preforming removed noncontributory material while retaining weight and maximizing color depth, and the final mixed brilliant faceting plan was executed with calibrated angles and symmetry tolerances to balance fire with color saturation. Throughout cutting and polishing, lap speeds, abrasive grades, and lap types were chosen to achieve an excellent polish without inducing thermal or mechanical stress, thereby maintaining the unenhanced status of the gem. Final grading documented carat weight, precise dimensions, mixed brilliant design, clarity evaluated at eye level, intense color intensity, and excellent polish, and this alexandrite is now offered through The Natural Gemstone Company with full disclosure of origin and enhancements, ready for setting in a design that will showcase its rare and technical attributes.
