1.48 Ct. Yellowish Green Cabochon Sapphire from Montana

This pear shape yellowish green sapphire weighs 1.48 carats, and measures 7.22 by 5.76 by 3.47 millimeters, and it is presented as a cabochon cut with semi translucent bodycolor and light color intensity, and it originates from Montana. The overall outline is a classic pear, with a well centered apex and gently tapering shoulders, and the dimensions create a balanced table to depth ratio for a cabochon, preserving both color and translucency. The Natural Sapphire Company presents this piece with full disclosure of enhancement, heat treated, which is a standard, stable treatment used to improve color saturation and to reduce certain inclusions, and the clarity grade is slightly included as evaluated at eye level, meaning inclusions are present but modest in visual impact under normal viewing conditions. The finish is described as excellent polish, and the lapidary work emphasizes smooth curvature and optical evenness across the dome to maximize the soft reflection and internal glow that cabochons are chosen to display.

As a cabochon, the cutting philosophy differs from faceted stones, and this sapphire demonstrates those differences in technique and outcome, the dome height of 3.47 millimeters provides sufficient curvature to reveal internal zoning and subtle color shifts without creating windowing, and the rounded profile reduces facet reflections in favor of a diffuse luster. The cutter preserved the pear outline with careful girdle shaping to ensure a uniform and comfortable seat in a bezel, and the apex is free of cutting nicks which speaks to the control and finishing skill applied during polishing. The slightly included clarity grade reflects small internal features that are consistent with natural growth, and these may appear as pinpoint inclusions or faint internal growth banding that sit beneath the surface and do not compromise structural integrity. Because the stone is semi translucent, these internal features contribute to character and depth, creating a lived in, organic appearance rather than the sharp sparkle of a faceted sapphire.

From a gemological perspective, this sapphire is corundum, and it shares the physical properties that make sapphire suitable for fine jewelry, including a refractive index in the expected corundum range which contributes to the way light is transmitted and diffused within the cabochon, and a Mohs hardness of 9 which provides strong resistance to abrasion when set correctly. Birefringence in corundum is low but measurable, and in cabochons with translucent material this can manifest as subtle doubling effects at certain viewing angles, while pleochroism in yellowish green material can cause the stone to display varying degrees of yellow and green tones depending on orientation and lighting. The declared heat treatment is used to stabilize and refine the yellowish green hue typical of Montana sapphires, and this treatment is permanent, widely accepted in the market, and disclosed here to maintain transparency. The specific gravity and density of corundum contribute to the substantial feel of the 1.48 carat piece relative to its size, making it feel appropriately weighty for its footprint.

For mounting and design, the stone is particularly well suited to bezel set rings or pendants where the rounded dome and softer reflections are showcased, and an open backed bezel can be used to allow light to transmit through the lower portion of the cabochon to enhance color. Yellow gold will warm the yellow components and intensify the green nuance, whereas white metals will provide contrast and a cleaner, more contemporary presentation, and the pear outline makes it an elegant choice for drop earrings when paired. Given the slightly included clarity, orientations that place internal features away from the primary face up viewing area will optimize eye appeal, and because of the excellent polish and durable corundum hardness, the sapphire is appropriate for everyday wear when set with protective metalwork. The Natural Sapphire Company can assist with setting recommendations, custom mounting options, and certification details to ensure this Montana cabochon is presented and protected in a way that maximizes its unique combination of color, translucency, and natural character.
