1.00 Ct. Green Sapphire from Madagascar

One beautiful transparent 1.00 carat round shape green sapphire, measuring 6.52 x 6.43 x 3.58 mm, with a mixed brilliant cut, intense color intensity, and an excellent polish, offers a compelling combination of gemological quality and aesthetic appeal. Sourced from Madagascar and offered by The Natural Sapphire Company, this sapphire exhibits a vivid green that is both saturated and balanced, providing a hue that reads as distinctly green rather than yellowish or bluish, under a range of lighting conditions. The mixed brilliant cut blends the light performance of a brilliant style crown with a more controlled pavilion faceting regime, producing lively scintillation and a pleasing face up appearance despite a slightly shallow depth, and the excellent polish enhances the contrast and brilliance produced by each facet junction. The stone has been heat treated, a stable and widely accepted enhancement in the trade for sapphires, applied to optimize color saturation and clarity, and to present a gem that is both beautiful and durable for everyday wear.

From a grading and clarity perspective this sapphire is described as very slightly included, evaluated at eye level, which to an educated buyer communicates that the inclusions are minor, do not materially affect transparency, and are not readily visible to the naked eye when the gem is set in typical jewelry. Very slight inclusions may take the form of tiny crystals or fine silk like features, which can serve as natural fingerprints confirming origin and natural formation, and unlike fracture filled material, these are stable and unaffected by the heat treatment that was applied. The gem’s transparency and mixed brilliant faceting deliver strong light return, so overall appearance benefits more from the cutting and polish than from internal features. With a Mohs hardness of 9, sapphire ranks among the hardest gem materials after diamond, making this green sapphire an excellent choice for rings, bracelets, earrings, and pendants intended for frequent wear, provided that standard care and occasional professional cleaning are observed. Ultrasonic cleaning is generally safe for heat treated sapphires, however, as with any natural gem, abrupt temperature changes and harsh chemicals should be avoided.

This 1.00 carat green sapphire adapts very well to a wide variety of custom jewelry settings, and The Natural Sapphire Company can advise on designs that balance protection with light performance. For maximum brilliance and a classic look, a four or six prong solitaire setting crafted in platinum or 18 karat white gold will secure the stone while allowing light to enter the crown facets freely. For a more protective option that still emphasizes color saturation, a full bezel setting in yellow gold or rose gold will wrap the girdle and reduce the risk of accidental knocks, a choice favored by active clients and those seeking a contemporary aesthetic. To increase perceived size and visual impact, halo settings with pavé shoulders amplify face up presence, while three stone configurations pair the center green sapphire with tapered diamonds or colored side stones for a narrative piece. For vintage inspired designs, a milgrain bezel or filigree gallery highlights the stone’s natural tone, while tension and low profile channel mounts create modern silhouettes for pendants and bracelets. Given the measured depth of 3.58 mm, setting craftsmen will recommend proper seat depth and prong length to protect the pavilion and maintain symmetry, and The Natural Sapphire Company offers bespoke design services, hand rendered proposals, and CAD visualizations so you can preview metals, setting styles, and side stone options.
