1.57 Ct. Greenish Blue Sapphire from Madagascar

This 1.57 carat oval greenish blue sapphire from Madagascar combines measured precision with exceptional natural beauty, making it an outstanding choice for a statement jewel. The stone measures 7.66 x 5.59 x 4.31 mm, a proportion that reads larger face up than many round stones of similar weight, and its classic oval silhouette flatters a wide variety of settings. Cut with a mixed brilliant style, the pavilion and crown balance step and brilliant facets to maximize both depth of color and scintillation, while the excellent polish ensures crisp facet junctions and lively light return. The color is intense, a sophisticated greenish blue that shifts subtly with viewing angle, and the clarity is graded as eye clean when evaluated at eye level, meaning there are no inclusions visible to the unaided eye that would distract from the gem s brilliance. Importantly for discerning buyers, this sapphire has received no enhancement, preserving its natural character and rarity.

From a gemological perspective this sapphire exhibits attributes that educated buyers prize, beginning with its origin. Madagascar has emerged over recent decades as a source of highly desirable sapphires, producing material with both saturated color and generally good clarity, and provenance from this region adds provenance value for collectors and clients who value traceable supply chains. The intense greenish blue tone in this stone is consistent with natural variance in corundum chemistry, and the mixed brilliant cut has been expertly executed to present the color evenly across the table while preserving weight in the girdle and pavilion. The eye clean clarity grade is particularly meaningful for a stone destined to be worn as a prominent center gem, because it allows unimpeded light transmission which enhances both brilliance and apparent size, without the need to rely on magnification to assess quality. The corundum mineral family ranks at nine on the Mohs hardness scale, making this sapphire highly suitable for everyday wear in rings and pendants, yet the combination of excellent polish and careful cutting reduces the likelihood of abrasion and chipping when properly set.

When considering design and setting, the dimensions and clarity of this sapphire make it an ideal centerpiece for a statement ring or pendant, where face up area and color saturation are critical. The oval outline naturally elongates the finger when set vertically in a ring, and the measured length to width ratio provides a pleasing balance that fits comfortably within a variety of mounting styles. Because the stone is eye clean and exhibits excellent polish, open settings with minimal metal coverage will show the gem to best advantage, while a well executed prong or claw setting will let light enter from multiple directions to maximize sparkle. For clients seeking a more contemporary look, a bezel setting can provide a sleek frame while protecting the girdle, and for those who want to emphasize color, a thin halo of small accent diamonds or contrasting metal can increase perceived size and presence without obscuring the sapphire s natural charm. The fact that this gem has no enhancement is particularly appealing to collectors and buyers who prioritize untreated gemstones, and The Natural Sapphire Company is pleased to present this example as part of a curated selection of responsibly sourced, untreated sapphires.

In summary this Madagascar greenish blue sapphire represents a rare confluence of weight, proportion, and clarity that is ideally suited to a prominent jewelry commission, whether a one of a kind engagement ring or a standout cocktail piece. Its 1.57 carat weight combined with the generous face up dimensions create a visual impact disproportionate to its carat figure, and the eye clean clarity allows the intense color to be appreciated without distraction. The mixed brilliant cut and excellent polish ensure dynamic light performance, and the lack of enhancement preserves the stone s natural identity and desirability. For clients who value documented origin, technical quality, and timeless beauty, this sapphire is a compelling choice, and The Natural Sapphire Company is available to advise on settings, design translations, and certification options to ensure the finished piece meets exacting standards.
