1.39 Ct. Green Sapphire from Madagascar

This 1.39 carat transparent oval green sapphire, sourced from Madagascar and offered by The Natural Sapphire Company, presents a precise set of measurements at 7.28 x 5.83 x 4.15 mm, and exhibits a balanced table to depth relationship that favors weight retention without compromising optical return. The gem is fashioned in an oval outline with a mixed brilliant cut, combining brilliant facets on the crown with more linear pavilion facets, and the finish is executed to an excellent polish that yields crisp facet junctions and minimal surface diffusion of light. Clarity has been evaluated at eye level as very very slightly included, with inclusions that do not detract from face up performance and that serve as natural identifiers for origin verification and long term valuation. Color has been graded as medium intense, a level that allows strong chroma while maintaining lively tone contrast across the facet planes, and this piece is provided with no enhancement, making its natural color and internal features fully original and stable.

From a cut engineering perspective, the oval silhouette combined with the mixed brilliant cut has been chosen to optimize light return and to control spread. The crown presents calibrated pavilion angles that direct incident light into multiple internal reflections, while the pavilion steps help to reduce light leakage and reinforce a deep green window free of washed out areas. The crown facets are proportioned to produce a focused scintillation pattern on movement, and the symmetry across the oval axis delivers even dispersion of flash and contrast. The medium intense green achieves a pleasing balance between color saturation and light transmission, which in a mixed brilliant architecture emphasizes both brilliance and color depth. The excellent polish enhances facet crispness and prevents micro abrasions that would otherwise scatter light, and the result is a gem that reads as lively and transparent under both natural daylight and artificial halogen viewing conditions.

When comparing this natural Madagascar sapphire to lab grown alternatives, there are several technical and long term advantages to consider. Natural sapphires carry trace element signatures and mineral growth structures that create subtle complexity in hue and pleochroism that are difficult to reproduce synthetically, and those internal growth characteristics contribute to the way light is scattered and absorbed, producing a depth of color and natural variance appreciated by connoisseurs. Because this stone is unenhanced, its color is intrinsic and stable, removing questions about the permanence of treatment that can affect value and wearability over time. In the market for fine gemstones, natural, untreated material from a recognized origin like Madagascar retains stronger secondary market demand, and its inclusions act as a fingerprint for laboratory verification and provenance documentation. Lab grown stones can offer excellent clarity and color at lower cost, but they lack the geological history and natural complexity present in a piece such as this. For collectors and clients seeking authenticity, long term value, and the nuanced interaction of light and natural zoning, this 1.39 carat green sapphire from The Natural Sapphire Company represents a technically compelling choice, combining expert cutting, documented origin, and the assurance of no enhancement.
