0.49 Ct. Yellowish Green Sapphire from Montana

This 0.49 carat round yellowish green sapphire from Montana combines technical precision with a distinct regional character, presented by The Natural Sapphire Company. The stone measures 4.86 x 4.82 x 3.10 millimeters, yielding a depth that is approximately sixty four percent of the diameter, a proportion that emphasizes return of light through the pavilion while preserving a lively crown scintillation. The cutter applied a mixed brilliant cut, pairing a brilliant styled crown with a more pavilion focused facet geometry, to balance fire and overall light return. The crown facets are arranged to produce tight, well defined star and kite reflections, while the pavilion facets are calibrated to direct light back through the table and crown, creating a compact pattern of scintillation that performs well under varied lighting. The girdle is stable and proportioned to facilitate precision setting, the symmetry is consistent with professional lapidary standards, and the polish is assessed as excellent, allowing unobstructed light transmission across the facet junctions.

Color and clarity are described with technical care, the gem presenting a yellowish green hue with medium color intensity that reads as a soft, verdant tone under neutral daylight. The hue sits within the range that collectors and designers prize for its subtlety, offering a versatile palette for both warm and cool metal pairings. At eye level the clarity grade is very slightly included, meaning that inclusions are minute and do not impinge on transparency or on the optical performance of the mixed brilliant faceting. These inclusions can act as internal identifiers of origin, and they contribute to the individuality of the piece without diminishing its utility as a center stone for fine jewelry. The material is transparent, and the combination of clarity and a controlled medium saturation produces a pleasing balance between body color and internal light play, avoiding the flatness of over saturation while maintaining presence and visual depth.

The sapphire has undergone heat treatment, a conventional enhancement applied to Montana sapphires to stabilize and refine color, and to reduce the visibility of minor inclusions, without compromising the inherent durability of corundum. Heat treatment in sapphire is a historically established practice, and when executed according to industry standards it yields a stable result that is consistent with long term wear and with the expectations of discerning buyers. The provenance of Montana links this gem to a distinct American lapidary heritage, where sapphires with pastel and greenish tones have been collected and set into heirloom pieces for more than a century. Historically these stones have been favored in personal jewels that reference landscape and place, such as sentimental rings and bespoke signet designs, and they remain a popular choice for connoisseurs seeking a sapphire with American origin and character. For clients seeking technical specification alongside artisanal provenance, The Natural Sapphire Company offers this gem with full transparency regarding its dimensions, cut type, clarity and enhancement, allowing jewelers and collectors to integrate it into pieces that respect both craft and history.
