1.50 Ct. Yellowish Green Sapphire from Madagascar

This 1.50 carat radiant shape yellowish green sapphire presents an exceptional balance of precise geometry and lively character, making it an attractive choice for the discerning buyer. Measuring 6.69 by 5.57 by 4.39 millimeters, this transparent stone displays intense color intensity and an excellent polish, and it is offered with no enhancement. The radiant cut is a hybrid design that combines the crisp angles of a step cut with the scintillation of a brilliant cut. In this example the facet arrangement has been optimized to maximize light return and scintillation, producing an active play of brilliance and dispersion across the table and crown. The truncated corners typical of the radiant profile create a compact silhouette that looks larger than its carat weight suggests, and the combination of strong transparency and rich, intense tone allows the yellowish green hue to read vividly in a variety of lighting conditions.

From a faceting and optical standpoint this sapphire is engineered to show light at its best, and the geometry of the cut contributes directly to perceived value. The radiant cut uses a dense grid of small crown facets and a carefully proportioned pavilion to break incoming light into a lively patchwork of reflections, improving both brightness and contrast. This approach increases scintillation, or the flashes of white light that attract the eye, while also enhancing color dispersion or fire, which is particularly effective in stones with a green component. The excellent polish further reduces surface light leakage, allowing more light to be internally reflected and returned to the viewer. For practical reference, settings that expose the pavilion to light and maintain a modest table size will allow this stone to exhibit its full optical performance, and the symmetrical facet geometry ensures an even, stable face up appearance without dark areas or uneven color zoning.

The clarity grade of slightly included, evaluated at eye level, is an important attribute to contextualize for an educated buyer. Slightly included indicates visible inclusions under close inspection, however in this example the inclusions do not significantly impede transparency or the passage of light, so the overall visual impact remains strongly positive. Under ten times magnification a trained grader would note internal characteristics typical of natural sapphires, and those characteristics are often considered part of the stone story by collectors. Crucially, this sapphire is unenhanced, meaning it has not been subjected to heat treatment or other common modifications to alter color or clarity. Untreated material from Madagascar is desirable in the marketplace, because Madagascar has become a notable source of high quality sapphires with attractive hues and provenance that appeals to collectors and connoisseurs. The combination of natural color, transparent body, and a polished radiant cut enhances rarity and long term desirability.

For an educated buyer considering both aesthetic and investment qualities, this stone offers several compelling attributes. The one point five zero carat weight is meaningful in the market, providing presence without sacrificing manageability for fine settings. The radiant geometry yields maximum light play which translates into outstanding wearable beauty, and the intense yellowish green saturation gives a unique color personality that works well in both contemporary and classic designs. From a durability perspective, sapphire is second only to diamond on the hardness scale among commonly used gemstones, making it suitable for everyday wear with conventional care. At The Natural Sapphire Company we emphasize transparent sourcing, careful gemological evaluation, and expert cutting, and this sapphire is presented with the contextual information that trained buyers rely on. If you prefer a particular mounting to emphasize table brilliance or to protect the stone while showcasing its color, our design team can advise on prong, halo, or bezel approaches that maintain maximum light flow. For further information on certification, facet diagrams, or recommended settings, our gem specialists are available to assist.
