1.12 Ct. Green Sapphire from Madagascar

This specimen is a transparent 1.12 carat emerald cut green sapphire, with precise dimensions of 7.02 by 5.12 by 3.08 millimeters, and a calculated depth ratio of approximately 50.7 percent, a proportion that preserves the stone's step cut geometry while optimizing return of light. The emerald cut presents a broad rectangular table with parallel step facets on the crown and pavilion, producing linear flashes rather than scintillation typical of brilliant cuts. Clarity is graded as very very slightly included when evaluated at eye level, indicating only minimal internal features that do not disrupt the gem's overall transparency. Color is described as medium intensity, exhibiting a pure green influence produced by iron incorporation within the corundum lattice, and the stone is unenhanced, providing a natural, stable hue directly from its Madagascar origin. The cutter achieved an excellent polish, resulting in sharp facet junctions and a smooth surface finish that minimize surface scattering and accentuate internal reflections.

The emerald cut structure of this sapphire is central to its distinctive sparkle. The large table and broad step facets create a controlled hall of mirrors effect, where alternating dark and bright bands run across the gem as it moves, generating depth and a refined play of light that is more architectural than flashy. The relatively shallow depth ratio keeps light paths short enough to favor strong return through the table, while the precise angles of the crown and pavilion facets, combined with corundum's refractive index in the range of about 1.762 to 1.770, maximize internal reflection and directional light recovery. Low dispersion in sapphire, approximately 0.018, yields subtle color separation, so the perceived brilliance relies on clean facet planes and optimal facet symmetry. The excellent polish reduces microfacet roughness, limiting scattering losses and producing crisp, mirrorlike reflections on each step. For connoisseurs seeking a restrained, elegant brilliance with structural clarity, this Madagascar green sapphire is an exemplary choice, and it is offered with full confidence by The Natural Sapphire Company.
