0.90 Ct. Yellowish Green Sapphire from Montana

This transparent 0.90 carat round yellowish green sapphire measures 5.58 x 5.64 x 3.80 mm, and is cut in a mixed brilliant style that combines a brilliant crown with a geometrically precise pavilion. The crown facets are calibrated to deliver lively scintillation, while the pavilion employs step influenced facets to control light leakage and reinforce depth of tone. The cutter has balanced table to girdle proportions and a slightly deep overall profile that favors saturated face up color without sacrificing return of light. Color is classified as medium intensity, exhibiting an attractive yellowish green balance that shifts subtly with viewing angle and lighting, a characteristic typical of Montana origin sapphires. The stone is heat treated, a stable and standard enhancement that improves uniformity of color and reduces undesirable zoning, and the polish is excellent, producing sharp facet junctions and crisp reflections across the table and crown.

Clarity is graded as very very slightly included, evaluated at eye level, and the internal features are best described as natural identifiers that add character rather than detract from beauty. Under magnification you will observe fine silk and a few minute pinpoint crystals and healed feather features, all of which function as a gemological signature, enabling provenance verification and long term tracking of the individual stone. These inclusions are positioned and oriented so they do not interrupt the main light paths, allowing consistent brilliance and scintillation in everyday wear. For the collector or the custom jeweler, these internal markers enhance the individuality of the sapphire, making it uniquely yours while still offering excellent polish and cutting precision. The Natural Sapphire Company presents this Montana sapphire as a technically interesting and wearable gem, ideally suited for a solitaire ring or as a colored accent in a bespoke design, where the mixed brilliant cut and the stone natural identifiers will be visible and appreciated by connoisseurs.
