0.69 Ct. Bluish Green Sapphire from Australia

This transparent bluish green sapphire is a cushion shape weighing 0.69 carat, with precise measurements of 5.79 x 4.48 x 3.50 mm. The gem is cut in a mixed brilliant style, designed to balance table brilliance with pavilion sparkle, and it displays an eye clean clarity grade when evaluated at eye level. Color is described as intense, with a saturated bluish green that exhibits depth and lively color response under typical lighting. The polish is excellent, resulting in crisp facet junctions and strong light return. The sapphire has undergone standard heat treatment, disclosed here for full transparency, a stable enhancement commonly used to optimize tone and saturation without compromising long term stability. Origin is Australia, and the combination of a compact physical size and intense color gives this stone a presence that belies its modest carat weight, making it suitable for refined, understated settings where color and clarity are the primary focus.
