0.44 Ct. Greenish Blue Sapphire from Montana

This specimen is a transparent 0.44 carat oval sapphire, measuring 5.16 by 4.20 by 2.76 millimeters, with a greenish blue hue and intense color intensity. The gem is fashioned in a mixed brilliant cut, combining a brilliant style crown with a complementary pavilion faceting scheme to optimize both scintillation and color saturation. Clarity is graded slightly included, evaluated at eye level, and the stone displays excellent polish across every facet plane. The piece has undergone standard heat treatment enhancement to improve color evenness and stability, and provenance is Montana, a source known for distinct cool blue and greenish blue tones. These core characteristics define the gem from a technical perspective, and they form the baseline for assessing optical performance, mounting options, and overall presence in finished jewelry.

Proportions are a key factor in this sapphire producing strong visual impact despite a moderate carat weight. The length to width ratio is approximately 1.23, which yields a slightly elongated oval profile that reads as substantial on the finger while maintaining classical symmetry. The pavilion depth of 2.76 millimeters relative to the average of the length and width leads to an overall depth of approximately 59 percent, a proportion that favors a balanced return of light into the viewer rather than excessive windowing or a dead center. The mixed brilliant treatment produces crisp facet junctions on the crown that deliver controlled flashes, while the pavilion facets are arranged to recycle light into the face and enrich the greenish blue chroma. Excellent polish and careful facet geometry reduce light leakage and increase apparent brightness, so the sapphire exhibits dynamic scintillation without losing the intense body color that defines its Montana origin.

The slightly included clarity grade evaluated at eye level indicates the presence of inclusions that are natural to corundum and do not materially compromise transparency or brilliance when set. In practical terms these inclusions are sufficiently minor and positioned so that light performance remains strong, enabling the gem to function as a focal point in a statement setting. At 0.44 carat the stone is compact yet optically potent, with dimensions that allow it to sit prominently in a solitaire engagement ring, a halo composition that magnifies perceived size, or a three stone design where the center sapphire anchors the composition. The combination of intense color and well controlled proportions means the gem reads larger than its carat weight might suggest when set in white metal or warm metal contrast, and the mixed brilliant faceting enhances fire and sparkle in movement. For clients seeking a piece with presence and technical refinement, this sapphire provides an excellent balance of color saturation, polished facets, and calibrated proportions.

At The Natural Sapphire Company we focus on translating these technical attributes into jewelry recommendations and precise mounting solutions. Our lapidaries and gemologists can advise on crown height and bezel clearance to protect the stone while maintaining maximum light return, or on the optimal prong arrangement to showcase the oval outline and avoid visual obstruction of the pavilion. Because the stone has been heat treated, routine care is straightforward, with gentle cleaning in warm soapy water and avoidance of sudden thermal shocks and harsh chemicals. We can supply a formal report detailing the measured dimensions, carat weight, cut description, clarity assessment evaluated at eye level, color grade, treatment disclosure, and origin. For buyers who prioritize craft, performance, and provenance, this Montana greenish blue oval sapphire represents a technically refined choice for a statement piece, and The Natural Sapphire Company is prepared to assist with bespoke mounting options and certified documentation.
