2.28 Ct. Yellowish Green Sapphire from Madagascar

This exceptional transparent yellowish green sapphire from Madagascar weighs 2.28 carats and is cut in a classic cushion shape, with dimensions 7.07 x 6.18 x 5.77 mm. It is faceted in a mixed brilliant style, combining a brilliant crown with a more varied pavilion to maximize both color saturation and light return. The clarity is graded as very slightly included, evaluated at eye level, meaning that under normal viewing conditions the stone appears remarkably clean, with only minor internal characteristics that do not detract from the visual performance. The color intensity is described as intense, and the stone has an excellent polish, which together produce vivid, stable color and lively surface reflection. Crucially for collectors and connoisseurs, this sapphire is untreated, no enhancement, preserving the natural crystal characters and long term value. The Natural Sapphire Company stands behind the origin and quality, and Madagascar is a well regarded source for sapphires with attractive tones and good crystal clarity, making this piece an appealing proposition for the educated buyer.

From an optical and grading perspective this sapphire exhibits the desirable combination of corundum durability and strong refractive behavior. Corundum typically has a refractive index around 1.76 to 1.77 and a dispersion near 0.018, which is lower than diamond, so sapphires show less fire but compensate with bright, crisp facet reflections and strong overall brilliance when well cut. The mixed brilliant cut on this cushion shape emphasizes scintillation across the table and crown, while preserving depth of color in the pavilion, producing a lively appearance that changes subtly with movement. Compared to other green or yellow green gems in its category, such as tourmaline, peridot, and garnet, this sapphire benefits from a higher refractive index and greater hardness, translating to stronger return of light and superior wearability. Tourmaline and peridot tend to have lower refractive indices and softer responses to facet patterning, so they can appear less lively under similar cuts. Tsavorite garnet can show impressive brilliance and intense green, but it has a different hue range and usually higher dispersion, resulting in a different sparkle character. The mixed brilliant cushion cut of this sapphire creates more lively facet flashes than a step cut, and its excellent polish ensures that light is reflected cleanly from facet to facet, enhancing apparent brightness without relying on dispersion based fire.

For an informed buyer, the combination of intense color, eye level very slightly included clarity, natural untreated origin, and excellent workmanship explains the value proposition of this gem. A 2.28 carat size in this attractive cushion format gives both presence and versatility for design, offering strong center stone impact in a ring, pendant, or bespoke piece, while the durability of corundum provides confidence for regular wear. Because there is no enhancement, the stone retains inherent rarity and collector appeal, and Madagascar provenance is often associated with well crystallized material that polishes to a fine finish. As an additional point of reference, if you appreciate gemstones that show internal play and color variability, consider the Semi Black Opal, which features a darker body tone that enhances play of color. The opal family produces iridescent flashes that are fundamentally different from sapphire brilliance, because opal displays diffraction based play of color rather than facet reflection, and opal requires more careful handling due to lower hardness and sensitivity to impacts and rapid environmental changes. In contrast this sapphire will deliver consistent reflective performance and resilience, making it suitable for daily wear jewelry.
