1.08 Ct. Bluish Green Sapphire from Montana

This 1.08 carat round bluish green sapphire from Montana exhibits transparent clarity and carefully measured proportions, dimensions of 6.08 by 6.09 by 4.02 mm, with a depth percentage of approximately 66.1 percent, making it an ideal candidate for a variety of precision settings. The cutting style is faceted, executed as a mixed brilliant cut, which combines a brilliant facet pattern on the crown with a complementary pavilion configuration to maximize return of light while preserving color saturation. At eye level the clarity is described as very slightly included, with minute inclusions that do not interrupt visual transparency and that serve to confirm natural origin under magnification, and the stone displays an excellent polish that lends crisp facet junctions and clean reflective planes. Color is an intense bluish green, a balanced combination of primary blue and secondary green that yields deep saturation and a medium to medium dark tone, and the stone exhibits subtle pleochroic behavior as the color shifts slightly between more saturated blue flashes and cooler green tones when the orientation changes, a characteristic that responds particularly well to oriented settings that allow the cutter and designer to control face up color.

The mixed brilliant cut employed in this sapphire emphasizes optical performance through a thoughtful facet architecture, the brilliant crown facets produce strong scintillation and lively contrast, while the pavilion faceting is calibrated to depth and angle to return saturated color without darkening the stone unduly, and the result is an intense color intensity with lively internal reflections. Heat treatment has been applied to this sapphire to enhance color uniformity and to stabilize tone and saturation, a standard and accepted enhancement in the trade that improves the gem s visual appeal and durability, and detailed inspection will reveal intact polish lines and well executed facet symmetry consistent with careful lapidary work. Given its round outline and balanced proportions, the gem sits well in both open prong mountings that favor light ingress and closed back settings that deepen color, and its transparency and very slightly included clarity mean it will read as visually clean in hands on viewing and photography, with internal features becoming visible only under loupe magnification.

For custom design pairing, this Montana bluish green sapphire is exceptionally versatile and rewards considered contrast and color harmony. A classic approach is a single stone solitaire in 18 karat yellow gold set with low profile four prongs to allow maximum pavilion light, complemented by a tapered shank of melee round brilliant diamonds in a small size to enhance sparkle and to provide a bright white contrast that lifts the bluish green. For a color forward composition, pair this sapphire with small round or trillion cut teal or green sapphires of slightly lighter tone to create a tonal cluster that emphasizes the subtle green component, or introduce a row of warm champagne diamonds or cognac sapphires to create temperature contrast that makes the blue component appear more vivid. For a modern architectural look choose a three stone setting with side baguette diamonds aligned on axis to the round center, or select two pear shaped Montana green sapphires in matching hue to form a dynamic symmetrical composition. The gem also responds beautifully to mixed metal designs, for example a platinum head to secure the stone and a rose gold gallery to add warmth to adjacent accents. At The Natural Sapphire Company we can advise on specific complementary gem dimensions and facet orientation to ensure the face up color and pleochroic response are optimized in your custom piece, and our artisans can recommend exact melee sizes, setting profiles, and metal choices that preserve the stone s excellent polish and showcase its intense bluish green character.
