1.17 Ct. Bi Color Sapphire from Montana

From the cold gravels of Montana to the patient hands of our cutters, this 1.17 carat oval bi color sapphire tells a quiet story of landscape and craft. Born in the rivers and benches where American miners first found blue and pastel gems, this stone carries the character of its origin in every facet. At 6.16 x 5.50 x 4.06 mm the oval outline is familiar and wearable, while the mixed brilliant cut translates rough contrast into lively light. The Natural Sapphire Company entrusted this material to master cutters who respected its natural zoning and coaxed a gentle, two tone personality from the crystal. Heat treatment was applied to stabilize and refine its hues, clarity was evaluated as very slightly included at eye level, and the polish was completed to an excellent finish. Those small internal marks are part of the sapphire story, proof that this is a natural gem that has traveled from riverbed to ring, and they sit well within the stone so that transparency and brilliance remain the dominant impressions.

How this sapphire will perform in real life is as much a part of its charm as its origin, and the mixed brilliant cut was chosen precisely to animate its bi color nature. In bright daylight the gem displays a fresh, light color intensity with facets catching cool lavender and warm golden tones depending on the angle, the oval shape creating broad flashes of color across the table. Under direct sun the pavilion angles throw lively scintillation, little bright pinpoints of white sparkle that contrast with the softer pastel washes of color. In warm incandescent or candlelight the golden component deepens and becomes more enveloping, producing a romantic halo effect, while cooler LED or fluorescent lighting lifts the violet edges and makes the stone appear more ethereal. Against a dark background or in low light the excellent polish preserves internal brilliance, and backlighting through an open setting will reveal the delicate bi color transition from crown to pavilion. For anyone seeking a wearable gem with a story, this Montana sapphire offers both provenance and performance, and The Natural Sapphire Company is ready to help you imagine it set so that its shifting colors are showcased at every moment.
