1.03 Ct. Greenish Blue Sapphire from Madagascar

This transparent 1.03 carat cushion shape greenish blue sapphire measures 5.84 x 4.59 x 4.06 millimeters, presenting a well balanced pavilion and table for its size. The stone has been fashioned with a mixed brilliant cut, integrating step facets on the pavilion with brilliant facets on the crown to yield controlled brilliance and a pleasing interplay of light. Clarity is graded as very slightly included when evaluated at eye level, providing a clean appearance to the naked eye while retaining natural internal characteristics that attest to the gem origin. Color is described as greenish blue with intense color intensity, a tone and saturation combination that produces depth without appearing dark under typical lighting, and the polish is excellent, delivering crisp facet junctions and lively reflection. Importantly this sapphire is reported as no enhancement, an attribute that preserves the natural state and optical behavior of the crystal, and the gem is documented as originating from Madagascar, a source known for producing a range of attractive sapphire hues with distinct local variation.

Beyond the technical specifications, the gem presents practical advantages for fine jewelry. At just over one carat and with compact dimensions, the cushion outline sits well in both classic and contemporary settings, offering versatility for bezel, prong, and halo designs. The mixed brilliant cut enhances table brilliance while maintaining color saturation through selective pavilion faceting, making this stone suitable for rings where both sparkle and color stability are desired. The very slightly included clarity grade indicates that the stone will set cleanly and read well in everyday wear, while the absence of enhancements minimizes concerns about treatment sensitivity during routine maintenance. For setting and care, standard precautions for corundum apply. Sapphires are among the harder gem materials, and this specimen will retain polish and resist abrasion in properly fabricated mounts, while professional cleaning and occasional inspection of the setting will help preserve both stone and mounting.

When compared to lab grown or synthetic sapphires, several distinctions of a natural, unenhanced stone become apparent. Natural sapphires form over geological time under variable conditions, creating a unique internal fingerprint of inclusions and growth features that provide provenance clues and individuality. These natural internal features often scatter and refract light in ways that are difficult to replicate in controlled laboratory growth, resulting in subtle complexity of color and light performance. The documented origin from Madagascar links this sapphire to a specific regional signature, and that traceable provenance contributes to its collectible and historical value. Natural, unenhanced stones also tend to command stronger secondary market recognition, as collectors and connoisseurs frequently value the rarity of an unmodified crystal and the story inherent in its natural formation.

In addition to aesthetic and rarity considerations, natural unenhanced sapphires offer predictable performance over time. Laboratory grown stones can match natural stones closely in hardness and initial appearance, however subtle differences in color zoning, pleochroism, and inclusional structure can affect long term perception and desirability for some buyers. Heat treatment and other enhancements are common in the trade to improve color and clarity, and while such treatments are accepted within the market, an unenhanced stone like this one provides assurance that the observed hue and clarity are original. This can simplify valuation and resale, and can be preferable for clients seeking an artisan quality and geological authenticity. At The Natural Sapphire Company we prioritize documented origin and transparent reporting, and we can provide further information about origin documentation and gemological assessment so clients can make informed choices.

Overall this 1.03 carat greenish blue cushion sapphire from Madagascar combines measured dimensions, a mixed brilliant cut, intense natural color, very slightly included clarity at eye level, excellent polish, and the significant attribute of no enhancement. These characteristics make it suitable for a refined jewelry commission where natural provenance and enduring performance are prioritized. The Natural Sapphire Company can assist with mounting recommendations and provide additional gemological documentation to support provenance and value assessment.
