0.57 Ct. Green Sapphire from Madagascar

This listing describes a single, transparent green sapphire weighing 0.57 carat, presented in a classic round shape with precise dimensions of 4.66 x 4.61 x 3.46 millimeters, cut by hand with a mixed brilliant style, graded with clarity described as very very slightly included evaluated at eye level, and exhibiting a medium color intensity and an excellent polish, originating from Madagascar, and enhanced by heat treatment. At The Natural Sapphire Company we prioritize clear, factual description so that an informed buyer understands exactly what they are evaluating, the provenance of the material, and the specific attributes that determine its value. The combination of a sub one carat weight with well balanced proportions and a fine polish makes this gem especially desirable for refined jewellery design, where optical performance and durability are equally important. The transparency of the stone is notable, and the clarity grade indicates minimal inclusions that do not detract from the gem when viewed under normal conditions, while the heat treatment is a standard and stable enhancement that has been disclosed to preserve full transparency and to improve the sapphire color to a uniform medium green that photographs and sets beautifully in a variety of metal colors.

The mixed brilliant cut is central to this sapphires optical signature, the cutter has balanced brilliant style facets on the crown with a more modified facet arrangement through the pavilion to marry scintillation with depth, this hybrid approach optimizes the way light interacts with the crystal such that incoming light is refracted and internally reflected in a controlled sequence, the crown facets and the table act as the initial refractive interface to break white light into spectral components and to create brilliant flashes, while the pavilion geometry returns that light back through the crown to the viewer, producing contrast and lively sparkle without sacrificing face up size. In a stone of these proportions, the cutter has maintained a relatively modest table and a proportionate pavilion depth to enhance face up brightness and to avoid a washed out appearance, the result is lively scintillation on movement, strong internal return of light that emphasizes the mid tone green, and attractive contrast patterning that reads as consistent even under varied lighting conditions. The excellent polish ensures that each facet boundary remains crisp, reducing surface diffusion of light and thereby preserving the clarity of reflections, this level of finish is particularly important in green sapphires where subtle hue components benefit from clean facet junctions and well executed symmetry.

Colour and clarity are both critical to the perceived value of this sapphire, the medium color intensity gives a pleasing balance between saturation and versatility, the tone is neither overly dark nor too pale, making it wearable in everyday jewellery and elegant in formal settings, the green hue in corundum is commonly associated with trace iron and the exact character of green can shift between bluish green and yellowish green depending on the relative presence of these elements, this gem presents a well centered green that reads true to the eye and photographs consistently, the disclosed heat treatment has improved both the color uniformity and the transparency which is a widely accepted practice in the marketplace for natural sapphires. The clarity assessment of very very slightly included evaluated at eye level signifies that any internal characteristics are minimal and typically only noticeable under magnification or upon very close inspection, for an educated buyer this translates to a stone that is effectively eye clean and which will not compromise the optical performance delivered by the mixed brilliant cutting style.

For practical considerations and for buyers looking for a gem worthy of a bespoke setting or thoughtful investment, this 0.57 carat round green sapphire offers a harmonious blend of cut quality, polish, and material origin, the dimensions of 4.66 by 4.61 by 3.46 millimeters allow it to sit comfortably in many classic ring, pendant, and stud designs while retaining a strong visual presence, the mixed brilliant cut maximizes both sparkle and perceived depth, the excellent polish underpins crisp reflectivity, and the Madagascar origin is recognized for producing stones with attractive color and good crystal quality. The Natural Sapphire Company stands behind the provenance and the full disclosure of enhancements, and we are prepared to provide any additional documentation or detailed imagery to assist in your evaluation, whether you are a connoisseur specifying a custom piece or a jeweller selecting a center stone for a signature design, this sapphire represents a carefully described and responsibly marketed example of natural colored corundum that performs well both visually and technically.
