1.44 Ct. Yellowish Green Sapphire from Montana

This oval shaped, transparent sapphire weighs 1.44 carats, and measures 8.36 by 5.84 by 3.73 millimeters. The stone exhibits a mixed brilliant cut with a classic oval outline, and a length to width ratio of approximately 1.43, which yields a balanced elongation that flatters most setting profiles. The measured depth of 3.73 millimeters corresponds to a depth of roughly 52.5 percent relative to the average girdle diameter, placing the cut within an excellent range for efficient light return and attractive face up spread. Color is described as yellowish green with medium intensity, the clarity grade is very slightly included when evaluated at eye level, and the finish quality is excellent polish. There is no enhancement, which confirms that this sapphire is in its natural state without heat treatment or other common interventions.

The mixed brilliant cut on this oval is engineered to combine the broad flash and dispersion characteristic of brilliant faceting on the crown, with a pavilion geometry tuned to recover light while minimizing leakage. The crown presents multiple kite and star facets arranged to break light into strong scintillation across the table, while the pavilion facet geometry is modified to the oval outline to preserve symmetry and contrast. The cutter appears to have oriented the pavilion depth to the crystal axis in order to enhance saturation and to conceal minor internal features, which is a deliberate craftsmanship choice when working with yellowish green material. Excellent polish indicates crisp facet junctions and clean facet planes, which reduces surface light scatter and increases apparent transparency and brilliance, especially in daylight and artificial white light environments.

Clarity characteristics consistent with a very slightly included grade and the specific eye level evaluation indicate that inclusions are small, isolated, and do not materially interrupt the light paths that create brilliance and scintillation. Such inclusions are often internal crystals or fine healed feathers, and in this example they are subdued by the cutter through careful facet placement, so they remain unobtrusive in face up viewing. The medium color intensity present in this sapphire provides a pleasing balance between saturation and lightness, allowing for strong face up brightness while retaining identifiable yellow and green components of hue. From a gemological perspective, yellowish green sapphires typically owe their color to trace amounts of iron within the corundum lattice, and medium intensity in this weight and size delivers an appealing color presence without appearing too dark or overly pastel.

The provenance of this sapphire, Montana, adds a significant layer of value and interest to the piece. Montana sapphires are renowned among connoisseurs for their range of natural pastel tones and for a historical reputation of yielding high quality, untreated material. Stones from Montana are often recovered from alluvial deposits, where the selective nature of natural transport frequently produces rough crystal that yields attractive clarity and color when cut. Surface and internal characteristics typical of Montana origin, combined with the absence of enhancement, align this sapphire with a growing market preference for verifiable, natural provenance. Collectors and designers value documented origin because it conveys geological story and rarity, and in many markets natural Montana sapphires command a premium relative to similar stones when origin can be established and when the material is unheated.

At The Natural Sapphire Company we emphasize both the gemological profile and the practical design considerations for setting and wear. The oval outline and the measured proportions make this sapphire versatile for solitaire rings, three stone layouts, and halo settings, where the mixed brilliant cut will interact with surrounding diamonds to produce lively scintillation. The medium color intensity adapts well to both warm yellow metal and cooler white metal mountings, with bezel and prong options available to protect the girdle while preserving bright face up appearance. For clients seeking a bracelet or pendant application, the stone’s balance of size, color, and clarity allows for confident use as a focal center stone. Because the stone is untreated and exhibits excellent polish, it is particularly attractive to buyers who prioritize natural gem materials and who seek an investment grade piece with provenance and artisanal cutting. If you would like a formal origin report, a detailed loupe photomicrograph, or bespoke design suggestions, The Natural Sapphire Company can provide additional documentation and setting proposals to match this sapphire to your exact specifications.
