1.64 Ct. Bluish Green Sapphire from Madagascar

This transparent 1.64 carat oval bluish green sapphire measures 7.54 x 5.46 x 4.59 mm and has been expertly fashioned with a mixed brilliant cut that balances scintillation and color saturation. The gem displays intense color intensity, leaning toward a teal influenced blue with green overtones that read differently under varied lighting, and it has an excellent polish that optimizes light return across the table and pavilion. The stone is natural, with no enhancement, which is a critical detail for both collectors and connoisseurs who prioritize untreated material. The mixed brilliant cut allows facets to interact in a way that enhances both depth of tone and lively sparkle, making this sapphire suitable for a variety of fine jewelry applications, from a refined solitaire ring to a custom pendant that showcases the stone face up and in profile.

In terms of clarity this sapphire is graded slightly included when evaluated at eye level, which is a common and acceptable range for natural sapphires of this color and origin. Slight inclusions in corundum can often serve as internal fingerprints of the stone that confirm natural formation, and they rarely compromise durability when the gem is properly set. The eye level clarity grading means that under unaided vision the stone appears clean to most observers, while closer inspection with magnification will reveal small features that are typical of natural Madagascar material. These slight inclusions can be used positively to tell the stone apart from synthetic or heavily treated material, and when combined with the gemstone s intense color and excellent polish, they contribute to an overall presentation that appeals to educated buyers who value authenticity over perfection.

The Madagascar origin of this sapphire adds an important layer of provenance and desirability. Madagascar is known for producing a diverse range of sapphire colors, including rare teal and bluish green tones that are increasingly sought after in the market. Specific mining regions in Madagascar have produced sapphires that show strong, saturated hues and good clarity, and collectors have grown to recognize the region as a source of distinct and collectible material. The fact that this 1.64 carat oval is untreated, with no enhancement, further enhances its market standing because untreated sapphires are less common and command a premium in private sales and auction settings. At The Natural Sapphire Company we document origin and treatment status carefully, and we encourage independent gemological verification to establish a clear record for future resale or appraisal.

From an investment perspective this sapphire offers several favorable attributes that support future appreciation. The combination of intense bluish green color, natural untreated status, and a weight above one and a half carats positions this gem in a segment of the market where supply is limited and demand is growing. Colored gemstone collectors and investors have shown a sustained interest in distinctive hues that are not mass produced, and Madagascar sapphires with natural teal or greenish blue tones have increasingly been recognized as scarce, making them attractive long term holdings. The mixed brilliant cut and excellent polish ensure that the stone will present well in jewelry, which is an important practical consideration for liquidity, because well cut and well finished pieces are easier to resell. For preservation and investment performance we recommend retaining original documentation, obtaining independent lab reports where possible, and choosing settings that protect the girdle and pavilion to maintain the gem s condition. At The Natural Sapphire Company we can assist with certification, bespoke mounting options, and secure storage advice, and we are available to discuss how this specific Madagascar sapphire fits into a diversified collection of natural, untreated coloured gemstones.
