1.75 Ct. Bluish Green Sapphire from Madagascar

This 1.75 carat bluish green sapphire presents an exceptional combination of precise proportions, clean clarity, and natural color, sourced from Madagascar and offered by The Natural Sapphire Company. The stone measures 7.63 by 5.69 by 4.07 millimeters, a set of dimensions that yield a depth of approximately 61.1 percent when calculated against the average of length and width, a proportion that balances face up presence with optimal light return. The gem is cut in a classical emerald cut, with broad step facets, a substantial table, and a controlled pavilion depth that together produce the characteristic hall of mirrors effect associated with high quality step cuts. Transparency is excellent, the clarity grade is eye clean at normal viewing distance, and color intensity has been evaluated as intense, delivering a saturated bluish green that reads vivid under both natural daylight and controlled lighting. The sapphire is untreated, no enhancement, a detail that preserves the natural chromophore balance and provides both rarity and long term stability.

From a cutting and optical engineering perspective the emerald cut chosen for this sapphire was executed to emphasize both color saturation and directional light performance. Emerald cuts rely on parallel step facets to create large planes of reflected light, and in this instance the faceter has retained broad, even facet symmetry along the crown and pavilion to avoid windowing and to promote strong color retention across the table. The long to wide ratio of approximately 1.34 produces an elegant rectangular silhouette that amplifies the bluish green hue when viewed face up, while the 61.1 percent depth supports a measure of internal light return that keeps the stone lively without becoming overly dark. The step facet geometry also moderates the appearance of any internal features, and because the stone is eye clean the reflection planes remain visually uninterrupted, allowing the viewer to appreciate the subtle zoning and pleochroic tendencies that cause the stone to exhibit slightly different blue and green responses as the viewing angle changes.

Craftsmanship and finish are key to the gemological performance of an emerald cut, and this sapphire displays an excellent polish and careful facet junctions that produce crisp facet outlines and sharp pavilion mirrors. The polish grade of excellent indicates minimal surface distortions and superior luster, conditions that enhance both the intensity and the perceived depth of the color. The absence of enhancement confirms that the color and clarity are intrinsic, a point that has a measurable impact on provenance value and long term desirability. For practical wear considerations the hardness rating of sapphire makes it well suited to daily jewelry, however the step cut creates softened corners that benefit from protective settings. Recommended mounting options include four prong settings with reinforced corner prongs, low profile bezels that protect the girdle and corners while preserving the rectangular geometry, and custom designs that orient the table to maximize face up color. The Natural Sapphire Company can advise on setting choices that maintain structural security while highlighting the intense bluish green palette.

As a gift the combination of natural origin, untreated status, technical precision, and striking color makes this sapphire an especially memorable choice for a significant occasion. The emerald cut communicates refined restraint and architectural beauty, a language ideal for an engagement stone or an anniversary gift for a recipient who values technical excellence and understated elegance. Presented in a simple bespoke setting the gem will read as both contemporary and timeless, creating a visual impact that is immediate when viewed and enduring over years of wear. For buyers who prioritize verifiable provenance and meticulous craftsmanship The Natural Sapphire Company provides gemological documentation and personalized consultation to match the stone with an appropriate mounting, ensuring the finished piece becomes a durable heirloom. For routine care use gentle soap and warm water with a soft brush, avoid harsh chemical cleaners, and have the setting inspected periodically to maintain the integrity of the mounting. If you seek a striking, technically superb natural sapphire that communicates intention and taste, this Madagascar sourced emerald cut bluish green sapphire is an exceptional candidate, and The Natural Sapphire Company is available to assist with certification, custom design options, and secure delivery.
