1.45 Ct. Bluish Green Sapphire from Montana

This is a superb GIA certified bluish green sapphire from Montana, weighing 1.45 carat, presented in a classic round shape with precise dimensions of 6.90 x 6.83 x 4.32 mm. The stone has been fashioned in a mixed brilliant cut to balance scintillation and depth, it carries a clarity grade of slightly included as evaluated at eye level, and its color shows a medium intense bluish green that is both lively and subtle. The gem is entirely natural with no enhancement, and it carries an excellent polish that contributes to a lively surface luster and refined facet definition. For an educated buyer, the combination of a reputable laboratory report, an unheated origin, and a Montana provenance creates a strong argument for long term value, because these qualities are precisely the attributes sought by collectors and connoisseurs when assessing natural sapphire rarity and integrity.

What truly sets this sapphire apart are the internal characteristics that form an unmistakable signature, a fingerprint of its natural origin. Montana sapphires commonly display a range of microscopic and visible inclusions that are not flaws in the aesthetic sense but rather evidence of the gem formation environment. In this stone you will observe fine, needle like features and delicate silk that scatter light internally to create a soft, velvety depth to the blue and green tones. There are also small crystalline growth features and subtle growth zoning that produce faint color banding when the gem is rotated under light, these features attest to a slow, complex crystallization process in a metamorphic host. The slightly included clarity description, evaluated at eye level, means that trained observation reveals these inclusions without severe distraction to the naked eye, and they actually enhance character by breaking up larger flashes of light into many small, lively facets of color. Trace elements such as iron and titanium are responsible for the bluish green hue, and the pattern and disposition of the inclusions are consistent with natural, unheated Montana material, giving this gem a provenance related beauty that is difficult to replicate by synthetic means.

From a practical and investment perspective this sapphire is exceptionally appealing to a discerning buyer. The presence of natural inclusions combined with no enhancement raises the stone’s desirability among collectors who prize untreated material, and its medium intense color sits in a range that is versatile for use in a variety of settings while maintaining noticeable color saturation. The mixed brilliant cut and the excellent polish optimize light return and mask certain inclusions, allowing the gem to sparkle attractively in a ring, pendant, or bespoke setting, while the corundum hardness rating of 9 ensures excellent durability for everyday wear when set thoughtfully. At The Natural Sapphire Company we emphasize clear documentation, and this gem’s GIA certification provides an independent verification of weight, dimensions, clarity description, and the unenhanced status, all critical details for appraisal and insurance. For those seeking provenance, character, and natural beauty combined with rigorous grading, this Montana bluish green sapphire represents a thoughtful balance of rarity, visual appeal, and gemological authenticity, and we are available to provide the full GIA report images and additional photographs to assist with assessment and setting choices.
