1.57 Ct. Green Sapphire from Madagascar

This 1.57 carat cushion shaped green sapphire is a finely articulated example of natural gem cutting and material quality, with dimensions of 6.40 by 5.92 by 4.61 mm and a calculated depth of 4.61 mm which produces a depth ratio of approximately 74.8 percent relative to the average girdle diameter, a proportion that promotes intense color saturation while preserving lively light return. The cutter employed a mixed brilliant cut combining a faceted brilliant style on the crown with step and modified facets on the pavilion, a design choice that enhances scintillation across the table and cushions the chromatic depth of the stone. Facet junctions display precise meeting points and consistent facet angles, and the excellent polish contributes to crisp facet reflections, which together yield pronounced contrast between bright flashes and deep color windows. The cushion outline has gently rounded corners and balanced symmetry, which reinforces even light distribution and makes the stone straightforward to set in a variety of mounting styles with minimal compensation for tilt or pavilion light leakage.

Optically the sapphire is transparent with intense color intensity and a well defined green hue that reads as a deep forest to teal green under different light sources, and the material exhibits subtle pleochroic behavior consistent with natural corundum where the orientation alters the perceived tone from greener to slightly bluer green. Clarity is graded slightly included when evaluated at eye level, meaning that internal features are present but do not dominate the visual appearance, and these inclusions function as natural growth signatures that verify authenticity and origin when examined by a trained gemmologist. The stone is untreated, documented as having no enhancement, so the color and clarity are entirely a result of natural geological processes within the Madagascar pegmatite and metamorphic environments where these sapphires form. The origin of Madagascar imparts particular trace element profiles, notably natural concentrations of iron and titanium and occasional vanadium zoning, which produce complex color interplay that cannot be perfectly replicated by synthetic processes. The excellent polish and careful facet proportions indicate that the cutter prioritized maximizing natural color while minimizing negative windowing and extinguished areas, resulting in a gem that performs with lively brilliance and deep, saturated green tones when mounted.

When comparing this natural Madagascar sapphire to lab grown equivalents, there are technical and intrinsic advantages to consider. Lab grown corundum can offer very clean material and uniform color, however it lacks the geological growth patterns and inclusion suites that provide both diagnostic value and aesthetic uniqueness in natural stones, so a natural 1.57 carat cushion from Madagascar presents a one of a kind internal fingerprint and minute color zoning which lend character and provenance. Natural stones, particularly untreated examples, retain collectible and investment attributes that laboratory grown material does not match in scarcity or long term market perception, and the untreated status here removes ambiguity about artificial diffusion or high temperature color modification, which preserves natural trace elemental relationships detectable by spectroscopic and microscopic analysis. From a craftsmanship perspective, cutters working natural rough must balance yield with color preservation and facet design to enhance true material beauty, an artisanal decision set that informs the personality of this particular stone and is absent in mass produced synthetics where cutters often operate to standardized templates.

As a representative of The Natural Sapphire Company I can confirm that this sapphire is offered with full disclosure of measurements, cut style, clarity evaluation, and enhancement status, and we provide gemmological verification to document its Madagascar origin and untreated condition. For connoisseurs who prioritize natural origin, geological complexity, and enduring value, this cushion shaped mixed brilliant green sapphire makes a compelling choice, as it combines an intense natural color, sound cutting proportions, and an excellent polish that will perform well in engagement and statement ring designs or as a collector specimen. We can advise on setting options that preserve light entry and face up saturation, and we will provide further imaging and magnified views upon request, ensuring that the technical and aesthetic priorities of knowledgeable buyers are fully addressed.
