2.79 Ct. Greenish Blue Sapphire from Montana

This is a transparent 2.79 carat fancy shape greenish blue sapphire, with precise dimensions of 9.42 x 8.85 x 5.39 mm, cut in a faceted brilliant style that maximizes light return and scintillation. The cutting style produces well defined facets and symmetry that emphasizes sparkle and optical performance, while the brilliant cut platform gives lively dispersion across the crown. Clarity is graded as very slightly included when evaluated at eye level, an important distinction for buyers who prioritize clean appearance without sacrificing natural character. Color intensity is described as faint, which in this greenish blue tone creates a subtle and sophisticated palette that responds beautifully to different metals and lighting. The polish is excellent, which tells a trained eye that the lapidary attention to finishing was meticulous, and the stone has not been subjected to any enhancement, a factor that materially increases its desirability among collectors and designers. Origin is Montana, and the provenance contributes both to the personality of the sapphire and to its market significance, as Montana stones are prized for their unique pastel and teal influenced hues.

The size and fancy shape of this sapphire make it exceptionally well suited to custom jewelry, especially for designs that require a statement center with refined proportions. At 9.42 by 8.85 mm the gem sits comfortably as a dominant center stone in rings, offering a generous table for faceting brilliance without overwhelming standard ring profiles. The depth of 5.39 mm indicates a manageable pavilion that allows secure bezel or prong settings while preserving the stone profile close to the finger for everyday wearability. Designers will appreciate the versatility of a fancy shape, which can read as contemporary or classic depending on orientation and mounting style, and which adapts elegantly to halo settings that amplify presence, to three stone layouts where it pairs with tapered baguettes or rounds, and to pendant or drop earring designs that benefit from a slightly elongated silhouette. For custom engagement pieces, the faint greenish blue color allows creative metal choices between warm yellow gold for contrast, rose gold for romantic softness, and platinum or white gold for a modern cool palette. The faceted brilliant presentation ensures that the gem projects lively reflections in movement, which is essential for pieces intended to be worn daily.

For an educated buyer assessing value, several objective factors make this sapphire notable. The weight of 2.79 carats combined with the clean transparency and very slightly included clarity grade gives the stone a balance of presence and eye clean appearance, which supports higher per carat valuation compared with more heavily included material. The absence of heat treatment or other enhancement is significant, as untreated Montana sapphires are comparatively rare in the market, and they retain stronger appeal for collectors and clients seeking natural provenance. The faint color intensity in a greenish blue tone is a hallmark of many desirable American sapphires, offering a unique aesthetic that differs from the saturated cornflower blues associated with other sources, and this nuance often commands a premium among connoisseurs. Excellent polish and precise faceting further augment value, since these factors directly influence light performance and perceived quality. Provenance from Montana adds traceable origin appeal, and for customers who require certification we recommend independent gemological reporting to document weight, dimensions, clarity observations, color description, lack of enhancement, and origin notes. The Natural Sapphire Company can assist with bespoke design consultations, setting recommendations tailored to the stone dimensions and depth, and additional imagery under varied lighting to support confident selection. For designers and buyers seeking an untreated, well finished, and proportioned sapphire that adapts to a wide range of custom settings, this 2.79 carat Montana greenish blue fancy shape sapphire represents a rare combination of natural character, wearable size, and technical quality.
