0.47 Ct. Greenish Yellow Sapphire from Montana

This specimen is a transparent 0.47 carat pear shape greenish yellow sapphire sourced from Montana, presented by The Natural Sapphire Company. The gem measures 6.00 by 4.22 by 2.50 millimeters, yielding a length to width ratio of approximately 1.42 and a depth that corresponds to roughly 49 percent of the average of the length and width. Those proportions produce a compact, well balanced pear outline that sits comfortably for jewelry applications while still offering a strong face up presence. The cutting style is described as mixed brilliant, with a brilliant facet arrangement on the crown and complementary pavilion faceting that is calibrated to enhance internal reflection and scintillation. Clarity is graded as very slightly included when evaluated at eye level, indicating minor natural inclusions that do not materially hinder transparency or the stone s ability to transmit light. The color intensity is light, and the piece displays an even greenish yellow hue through the table, supported by an excellent polish that yields crisp facet junctions and lively surface reflections. The sapphire has been heat treated, a standard enhancement that stabilizes and refines color, and the Montana origin contributes to its distinctive pastel spectrum.

Technically, the mixed brilliant faceting employed here optimizes the trade off between dispersion and color saturation. On the crown the cutter has used a traditional brilliant facet pattern, with a controlled table opening and well proportioned star and bezel facets that break incident light into small flashes of white brilliance. The pavilion has been tailored to the pear outline, with modified facets that channel light back through the crown in a manner that maximizes return rather than leakage. The result is a lively pattern of scintillation during movement, combined with a broad flash face up that communicates the stone s light tone. Facet alignment and symmetry are critical in pear shapes where the tapered point and rounded terminus must balance to avoid a dark bow tie effect. In this example the facet junctions are symmetrical along the long axis and the girdle line is consistent, supporting even table illumination and minimizing undesirable windowing. The excellent polish further refines the optical presentation by producing sharp, mirror like facet surfaces that enhance contrast and crispness between bright and dark areas.

From a clarity and color science perspective this greenish yellow tone is consistent with trace concentrations of iron, and in some cases minor titanium, which influence the absorption characteristics in the visible spectrum. The light intensity classification indicates a delicate balance between hue and tone, producing a soft, pastel like appearance that is highly sought after in certain collector and bespoke jewelry markets. The very slightly included clarity at eye level means that under direct observation small internal features can be identified by a trained eye, but these features are not obtrusive and do not interrupt the stone s overall transparency. Heat treatment has been applied to enhance color evenness and to reduce the visual impact of some internal features, a treatment that is stable under normal wear conditions and commonly accepted in the trade. Montana origin often correlates with a particular range of cool to soft greenish and yellowish tones, and this piece exhibits those regional characteristics, providing provenance value in addition to its aesthetic attributes.

As a centerpiece this 0.47 carat pear sapphire is exceptionally well suited to settings that emphasize its cut and optical performance. Because the cut returns substantial light and the polish is excellent, open settings that allow light to enter through the pavilion will maximize brilliance and face up sparkle. A solitaire or a three stone composition with white metal accents will provide strong contrast to the greenish yellow hue and amplify scintillation, while a halo of small white sapphires or diamonds will increase perceived size and enhance fire without overpowering the pastel color. For collectors seeking a distinctly American provenance and a finely proportioned mixed brilliant pear, this sapphire from The Natural Sapphire Company represents a refined choice, combining precise cutting geometry, stable enhancement, and carefully evaluated clarity.
