A striking 1.585 ct. green-yellow sapphire with a bright, lively presence thanks to its light tone and vivid saturation. Expertly cut in a classic oval, this gem delivers excellent scintillation, flashing light across the entire surface with even the slightest movement. At this size, Montana sapphires are rarely this clean—this stone is clean at 10× magnification, making it an exceptional find for collectors and designers seeking premium material from the Treasure State.
