The contrasting colors give this sapphire an unusually dynamic personality, shifting from an earthy, subdued green into softer purple and pink tones as the light changes.\u003c\/p\u003e\n\u003cp\u003eCut into a modified cushion brilliant, the stone combines a nearly square outline with lively faceting designed to bring out its brilliance and changing color. At 8.11 × 8.08 mm, it also has a beautifully balanced face-up presence, making it an exceptional candidate for a one-of-a-kind ring or collector piece.\u003c\/p\u003e\n\u003cp\u003eThis sapphire originates from the El Dorado Bar deposit in Montana, USA, an alluvial sapphire deposit associated with the Missouri River region. Montana sapphires have become especially sought after for their distinctive colors and American provenance, with stones showing unusual color behavior occupying an even more specialized niche.\u003c\/p\u003e\n\u003cp\u003eMost importantly, this sapphire is completely untreated and accompanied by a GIA report, documenting its natural sapphire identity and characteristics. The combination of its 3+ carat size, American origin, lack of treatment, unusual color change, and GIA documentation makes this an especially compelling Montana sapphire.\u003c\/p\u003e\n\u003cp\u003eFor the collector or designer looking beyond traditional blue sapphire, this stone offers something genuinely different: American origin, natural untreated color, and two dramatically different personalities in a single gemstone.\u003c\/p\u003e","brand":"Caleb B.
