1.63 Ct. Yellowish Green Sapphire from Madagascar

The Natural Sapphire Company is pleased to present a beautiful transparent yellowish green oval sapphire weighing 1.63 carats, a size that immediately communicates premium quality to the informed buyer. This gem measures 6.80 by 5.74 by 4.97 millimeters, offering a pleasing face up presence for its weight class, and it is fashioned in an oval shape with a mixed brilliant cut, a design choice that combines pavilion faceting optimized for light return with a crown arrangement that enhances perceived depth of color. The sapphire displays intense color intensity, a trait that signals a saturated and desirable hue that performs well under both natural and artificial lighting. Its clarity is graded as very very slightly included when evaluated at eye level, meaning the stone presents with minimal, well distributed internal features that do not interfere with brilliance or visual appeal, and the polish is excellent, so facet junctions are crisp and reflections are clean. This stone has been heat treated, a stable and widely accepted enhancement that improves tone and clarity, and its documented origin is Madagascar, a deposit known for producing a wide range of attractive, collectible sapphires.

The carat weight of 1.63 carries a great deal of significance for collectors and connoisseurs, because it sits at a threshold where both presence and versatility meet. In sapphires, as with other gem corundums, each tenth of a carat can materially influence market value, and a 1.63 carat gem commands greater attention than smaller sizes, while remaining highly practical for a variety of ring and pendant designs. The measurements of 6.80 by 5.74 by 4.97 millimeters yield a balanced spread, enabling a generous face up area that maximizes the visual impression of size without sacrificing structural stability. The mixed brilliant cut further contributes to an ideal balance of scintillation and color saturation, making the weight translate into optimal visual impact. For an educated buyer assessing value, this is a stone that combines desirable carat weight with superb proportions, delivering both immediate aesthetic reward and enduring desirability as part of a curated collection.

Clarity, color, treatment, and origin are the primary axes by which gem quality is judged, and this sapphire performs strongly on each. The very very slightly included clarity grade evaluated at eye level indicates that inclusions are minute and do not materially affect the stone when worn, a category that approaches loupe clean appearance for many observers while remaining natural and identifiable to gemmological study. The intense color intensity speaks to strong chroma, where the yellowish green hue sits with a lively saturation that reads as sophisticated and somewhat rare in the market, appealing to buyers who value distinctive yet wearable tones. Heat treatment is noted, and it is important to emphasize that controlled heating is the historical standard in improving corundum color and clarity, an accepted practice that yields stable results that will endure normal wear. Madagascar as the documented origin provides additional provenance value, the island being recognized for producing gems with attractive complex hues and for the potential of distinctive zonal color effects that can give a gem unique personality. All of these factors together form a transparent narrative a buyer can evaluate, and they contribute to the stone being a coherent, verifiable offering rather than an anonymous commodity.

From a practical and investment standpoint, this 1.63 carat yellowish green sapphire from The Natural Sapphire Company is an excellent candidate for a signature ring, a refined pendant, or a bespoke design where the stone is allowed to be the star. The mixed brilliant oval shape is particularly suited to solitaire settings that emphasize sparkle, or halo designs that enhance perceived size while protecting the girdle and corners. The depth of 4.97 millimeters provides sufficient material for secure bezel or prong work, and the excellent polish ensures that metalwork will reflect cleanly from the facets. For the discerning buyer this sapphire represents a thoughtful combination of measurable quality points, including carat weight, balanced dimensions, intense color, near clean eye level clarity, and stable heat enhancement, all supported by a documented Madagascar origin and the assurance of responsible sourcing. When purchasing through The Natural Sapphire Company, clients receive not only a well documented gem but also the expertise to advise on mounting, care, and long term stewardship, making this sapphire both an immediate pleasure to wear and a considered addition to a curated collection.
