2.17 Ct. Greenish Blue Sapphire from Montana

This 2.17 carat, transparent, greenish blue sapphire presents a precise and measured presence, with calibrated dimensions of 8.75 by 8.45 by 4.85 millimeters. Cut in a faceted fancy outline using a modified brilliant schema, the faceting pattern employs a mix of kite and triangular crown facets radiating from a well defined table, paired with a carefully angled pavilion that returns light with controlled scintillation. The stone exhibits a medium color intensity that reads as an even greenish blue across the crown, with balanced saturation that avoids overly dark tones while maintaining a strong perceptible hue. Clarity is graded as very slightly included evaluated at eye level, which in practical terms means minor internal features are present but do not materially interrupt transparency or light performance when the stone is set. The polish is excellent, delivering crisp facet junctions and mirror like facet planes that enhance both contrast and brilliance. Importantly for the technically minded buyer, this sapphire is untreated, with no enhancement, and is a natural Montana origin specimen, attributes that materially affect both long term value and collector desirability.

From a gemological performance perspective, the modified brilliant faceting applied to this fancy shape has been executed to optimize both internal light return and surface brilliance. The crown facet angles and pavilion depths have been balanced to yield an approximate overall depth equivalent to roughly fifty six percent of the average diameter, a proportion that supports a lively mix of scintillation and face up spread. The medium intensity of the greenish blue body color is complemented by a transparency that approaches gem quality, allowing internal facet patterning to contribute to the visual complexity rather than being obscured by cloudiness. The very slightly included clarity grade permits excellent durability and polishability, enabling the cutter to achieve the excellent finish seen on the girdle and facet junctions. Montana sapphires commonly exhibit subtle pleochroism between blue and green axes, and this piece demonstrates that effect in a refined manner, offering slightly different tonal emphasis under directional light while retaining its core greenish blue identity. The absence of heat treatment or other enhancements ensures that the color, pleochroism, and inclusion character are all natural, which is critical for specialists who assess stones on geological and provenance criteria.

Ethical sourcing and traceability are central to how this sapphire will sit in a conscious consumer portfolio. The Natural Sapphire Company sources Montana material through established partnerships with local miners and intermediaries who adhere to traceable supply chain practices, and the untreated nature of this gem minimizes interventions between the mine and the finished stone. For the buyer concerned with environmental stewardship and social responsibility, this piece illustrates how technical excellence in cut and polish can coexist with a provenance that respects small scale mining communities and minimizes unnecessary processing. From a practical wearer perspective, corundum hardness and the technical integrity of the cut make this sapphire well suited to everyday jewelry applications, including secure ring settings and bespoke designs where the faceting and color can be displayed prominently. The stone is ideal for collectors who catalog pieces by origin and treatment status, and for designers who require predictable optical behavior when integrating a center stone into a calibrated setting.
