1.28 Ct. Bluish Green Sapphire from Montana

This cushion shaped sapphire weighs 1.28 carats and measures 7.08 by 5.14 by 4.16 millimeters, making it an ideal size for a single stone engagement ring or an accent center for a refined pendant. The stone is faceted with a mixed brilliant cut, a design chosen to balance maximum light return with a broad and flattering table face. The cutting displays an intention to preserve weight while optimizing color, and the finished gem exhibits an excellent polish that creates clean, mirror like facet surfaces. Clarity is graded as very slightly included when examined at eye level, a grade that maintains the stone as effectively eye clean while allowing natural internal features that attest to its authenticity and origin. Color presents as a distinct bluish green with dark intensity, a tone that reads as deep and saturated in most lighting, and the sapphire has been heat treated to enhance and stabilize its hue, a standard, permanent, and widely accepted enhancement for fine corundum. This gem comes from Montana, and is offered by The Natural Sapphire Company, whose cutting and grading standards ensure the measurements and descriptions here accurately reflect the stone you will receive.

The mixed brilliant cutting style employed on this cushion sapphire combines the scintillation of brilliant facets on the crown and pavilion with the larger, step like planes that support the cushion outline, producing a lively internal play of light that complements the stone body color. On the crown, a proportioned table and well angulated star facets work with a series of pavilion facets to generate return flashes and a pleasing pattern when the piece is moved under light. The cushion outline moderates the brilliance pattern by softening the transitions at the girdle, while careful facet junction alignment and an excellent polish maximize contrast and minimize unwanted light leakage. The 4.16 millimeter depth relative to the stone dimensions yields a depth that supports the dark, saturated bluish green tone rather than letting the gem appear washed out, and the cutter has prioritized facet placement to preserve the rich hue while allowing for controlled scintillation. These cutting decisions are technical and deliberate, reflecting the cutter intention to balance optical performance with weight retention, an important consideration when sourcing a natural Montana sapphire of this size and character.

Color is the defining attribute of this sapphire, and the bluish green tone with dark intensity creates a strong visual presence that will command attention in any setting. The stone shows a nuanced mix of blue and green chroma that shifts subtly with viewing angle and light source, a pleochroic behavior common to corundum that is especially engaging in teal to forest green ranges. The dark color intensity enhances the perceived depth and richness of the tone, producing a jewel that reads as sophisticated and dramatic rather than pastel or muted. Because the piece was heat treated, the color has been permanently improved and stabilized, making it suitable for everyday jewelry use without concern for fading or further alteration under normal conditions. The very slightly included clarity grade means internal features are present but not prominent at typical viewing distances, adding a natural fingerprint to the stone that collectors often appreciate, and the excellent polish ensures those internal characteristics do not distract from surface brilliance.

When set, this Montana sapphire will stand out in any jewelry setting because of its saturated bluish green body color, its thoughtful mixed brilliant cutting, and its fine finish. For maximum color emphasis, an open prong setting or a low profile bezel with a slightly open back will allow light to enter and enliven the stone, while a halo of small brilliant cut diamonds will create contrast that makes the deep teal tones appear more vibrant. White metals bring forward the cooler blue aspects of the stone, while yellow gold will warm the green notes for a different character, and platinum will provide a modern, high contrast backdrop that emphasizes the jewel tone. The cushion silhouette lends itself to both classic four prong mounts and more contemporary bezel or mixed metal designs, and the 1.28 carat weight offers versatility from a substantial solitaire to a coordinated stack with accent stones. Durability is assured by the inherent hardness of corundum, making this gem suitable for rings and daily wear with standard care practices. For buyers seeking a distinctive, technically well executed sapphire with a bold bluish green presence, this Montana cushion sapphire is an excellent choice, and The Natural Sapphire Company stands ready to assist with custom mounting options, detailed imagery, or further technical information to ensure the final piece showcases the stone to its fullest potential.
