5.06 Ct. Green Sapphire from Madagascar

This sapphire is a technical exemplar of proportion and polish, C.Dunaigre certified, weighing 5.06 carats, with exact dimensions of 11.14 millimeters by 8.38 millimeters by 5.54 millimeters, and presented in an emerald cut, a rectangular step cut with truncated corners. The faceting plan follows classical step cut geometry, with broad parallel crown and pavilion steps that create a hall of mirrors effect, and a generous open table that permits direct appraisal of body color and internal character. The measured depth relative to the average of the length and width yields a depth of approximately 56.8 percent, a proportion that balances depth and face up presence to maximize even color delivery and preserve weight for an impressive carat size without sacrificing light return. The gem has been evaluated at eye level and assigned a clarity grade of very very slightly included, indicating that inclusions are minimal and are not readily apparent to the unaided eye, and the polish is graded excellent, with crisp facet junctions, smooth facet planes, and a finish that optimizes contrast and luster. Origin is Madagascar, and the stone has been heat treated, a stable and well established enhancement that intensifies the blue green hue while maintaining natural crystal integrity, provenance, and trace element signatures as documented by the accompanying certificate.

Color is the dominant technical attribute of this stone, described on the certificate as blue green with vivid intensity, a saturation level that places the stone in the upper echelon of green sapphire color categories. The emerald cut accentuates the uniformity of hue across the crown and table planes, while the step facets create interplay between deep core color and lively flashes along the facet edges, giving the appearance of layered depth rather than surface color alone. Under direct viewing, the stone presents a deep coastal teal at face up, moving to a richer forest green under oblique viewing, consistent with dichroic tendencies found in many corundums, yet with very even color zoning indicating that the cutter oriented the table relative to the crystal axis to maximize color homogeneity. Vivid intensity here denotes both robust saturation and a medium to slightly deep tone, an optical equilibrium where the sapphire retains brilliance and legibility of internal features while projecting a dense, jewel like color that reads as both elegant and dramatic in finished jewelry applications.

Clarity and cutting technique together define how this sapphire communicates its color and depth, and the craftsmanship is deliberately oriented to show clarity rather than mask it. The very very slightly included grade, assessed at eye level, implies that inclusions are principally minute and well confined to planes or localized areas that do not interrupt the open table view, and that the cutter used the step cut format to reduce windowing effects while preserving weight. The emerald cut enables long parallel facets that emphasize the stone stature and create flash lines that move with the hand, a characteristic that is particularly desirable in larger stones intended as centerpieces. The excellent polish ensures minimal light scattering at the surface, so reflections remain sharp and the overall appearance is a combination of velvety depth and precise facet defined highlights. Heat treatment is disclosed and stable, used to refine the blue green balance and to improve clarity by reducing the visual prominence of any fine silk or microscopic inclusions, an industry accepted technique that when properly executed preserves the gem mechanical stability and color permanence. The Natural Sapphire Company provides the full certificate documentation and provenance, so the technical shopper can trace origin, treatment, and the specific gravimetric and dimensional measurements that support appraisal, setting design, and insurance valuation.

There is also a romantic provenance embedded in the technical attributes, a narrative that speaks to color and clarity as metaphors for devotion and fidelity. Imagine two travelers meeting along a Malagasy lagoon, the water between them reflecting a blue green that holds both the coolness of ocean and the warmth of verdant shoreline, a color echoed in this sapphire as vivid blue green. The stone clarity acts as a pledge, very very slightly included yet visually uncompromised, akin to a promise that acknowledges small imperfections while remaining transparent and true. The step cut becomes the architecture of that promise, each parallel facet like a written vow repeated and reflected, the open table like an open heart, and the depth proportionality like balance maintained over time. For an engagement setting, this gem will read as a timeless token, the blue green hue referencing both sea and forest, the heat treatment seen as a refinement of shared experience, and the excellent polish offering the daily brilliance that mirrors small acts of care.

Practical considerations for setting and display are informed by the measurements, weight, and faceting style, and The Natural Sapphire Company can advise on ideal mounting choices to preserve optical performance. The rectangular emerald cut proportions of 11.14 by 8.38 millimeters suit classic four prong or bezel treatments that emphasize table exposure while securing the truncated corners, and the depth of about 56.8 percent supports a low to medium profile setting that keeps the gem close to the hand while allowing the step facets to breathe. Complementary accents can include a narrow halo of high clarity white diamonds to increase perceived brightness without overpowering the blue green saturation, or a simple solitaire in warm yellow metal to warm the perceptual tone and create a vivid contrast. For collectors seeking control of light interaction, a bezel with a thin open gallery will protect the stone while permitting side light to enter the pavilion steps, enhancing the layered color effect. The Natural Sapphire Company stands behind provenance, certification, and mount recommendations, and can provide bespoke design consultation to translate the technical virtues of this Madagascar emerald cut green sapphire into an heirloom quality piece that communicates both technical excellence and a deeply resonant romantic story.
