1.60 Ct. Greenish Blue Sapphire from Montana

One beautiful transparent 1.60 carat round shape greenish blue sapphire, precisely proportioned at 7.01 by 7.07 by 4.60 millimeters, is presented with a mixed brilliant cut that balances scintillation and depth. The mixed brilliant style combines a faceted crown arrangement with a pavilion optimized to return light, producing a lively interplay between flashes and depth through the table. Clarity is graded as very slightly included, evaluated at eye level, meaning that minute internal characteristics are present under magnification but do not detract from the gem s overall transparency or visual impact to the unaided eye. The stone exhibits intense color intensity, translating to a saturated, consistent hue across the face and through the pavilion, and the finish is rendered to an excellent polish standard, providing crisp facet junctions and a smooth, reflective surface. This sapphire has been heat treated to enhance stability and color, a widely accepted and well documented treatment in modern gemology, with the enhancement disclosed fully.

The greenish blue coloration of this sapphire is rich and bold, a tonal quality that reads as a symbol of personal power and distinction while remaining versatile in contemporary and classic jewelry designs. The hue sits in a distinctive region of the color spectrum where blue and green blend with sufficient saturation to present a strong visual identity, yet with enough neutrality to coordinate with a range of metals and complementary gemstones. The intense saturation and the mixed brilliant cutting strategy together emphasize both brilliance and color depth, producing strong contrast between light return and the darker core, which enhances perceived depth and presence when viewed face up. At 1.60 carats and the given dimensions, the proportioning supports a substantial face-up appearance without excessive depth loss, allowing the stone to convey both visual weight and refined balance on the finger. Sapphire s inherent hardness and toughness contribute to practical wearability, permitting confident daily use when set appropriately, while the excellent polish ensures that facet reflections remain clean and well defined, maximizing the stone s ability to project light and color.

Originating from Montana, this sapphire carries a provenance associated with the geological conditions of that region, where emplacement and metamorphic processes yield sapphires with a distinctive character. Montana sapphires are known among connoisseurs for their particular range of tones and often subtle, complex coloration, and this greenish blue example reflects those geological signatures.
