1.61 Ct. Greenish Blue Sapphire from Montana

This transparent 1.61 carat oval greenish blue sapphire offers a compelling combination of weight, dimensions, and color that make it an exceptional candidate for a high end gemstone collection. The stone measures 7.75 by 5.58 by 4.55 millimeters, presenting classic oval proportions that are versatile for a range of mounting styles. The overall presentation is clean and precise, with an intense color intensity that reads as a balanced mix of blue and green, and a transparency that allows for clear light transmission. Origin is Montana, a source known for producing sapphires with unique teal and greenish blue tones, and this material displays the geographic character expected from that provenance. The Natural Sapphire Company offers this sapphire as a specimen that sits well within the spectrum of collector grade gems, combining natural origin, market friendly size, and a hue that is distinct without sacrificing purity.

The gem has been fashioned in a mixed brilliant cut, an approach that combines a brilliant style crown with a faceted pavilion intended to optimize both dispersive sparkle and depth of color. The cutter has executed a refined facet schema, with precise crown facets that channel light into the pavilion, and pavilion facets that are tuned to return light through the table while also preserving saturation. Proportions yield a depth of approximately sixty eight percent calculated relative to the average of the length and width, supporting strong face up presence without appearing shallow or overly deep. Girdle thickness and symmetry are consistent, and facet junctions are sharp, which enhances crisp scintillation and defined light patterning. The polish has been evaluated as excellent, producing clean luster across the crown and pavilion facets, and minimizing surface disturbances that can detract from optical performance.

Color and clarity attributes align in a way that will satisfy connoisseurs who appreciate nuanced material. The hue is best described as greenish blue with a dominant blue component and a noticeable green modifier under varied lighting, yielding a teal leaning appearance that is especially characteristic of Montana sapphires. Intense color intensity is present, which provides vivid saturation while maintaining clarity and allowing the internal light path to remain open. Clarity is graded as very very slightly included when assessed at eye level, indicating inclusions that are minor, well localized, and not visually disruptive in standard viewing conditions. These internal features do not compromise durability, and they contribute to the gemological fingerprint that can assist in identification and provenance documentation. The sapphire has been heat treated, a stable and widely accepted enhancement that improves color uniformity and reduces the visibility of certain inclusions, while preserving the natural crystalline structure and overall integrity of the stone.

For collectors and high end jewelers considering integration into a portfolio or a bespoke setting, this sapphire offers practical advantages and aesthetic flexibility. Its 1.61 carat weight and oval silhouette respond well to both solitaire and halo designs, and the mixed brilliant faceting favors bright face up appeal in settings that allow light to enter from multiple angles. The intense yet cool tonality pairs elegantly with white metals to accentuate blue depth, and also with warmer tones if the objective is to highlight green nuances. From an investment and collection perspective, material with clear origins, documented treatment, and top level craftsmanship is desirable, and The Natural Sapphire Company provides provenance support and condition verification. This piece is well suited as a center stone for a signature ring, as the focal point in a pendant, or as a collectible specimen for a connoisseur who values precise cutting, stable enhancements, and the distinctive color character of Montana sapphires.
