This 1.39 carat heart-shaped sapphire is a product of Chanthaburi, Thailand, entirely unheated. The color is a deep, rich green with strong saturation held evenly across the heart-shaped face. The heart cut is a genuinely uncommon shape for sapphire, requiring careful symmetry to achieve a clean, well-defined cleft and two even, balanced wings – a more demanding cutting choice than a standard oval or cushion. Clarity is excellent, with the stone reading clean to the eye and good transparency throughout. In hand it's lively, with solid brilliance returning across the facets. The color is entirely natural, with no heat treatment applied, confirmed by a Chanthaburi Gemological Laboratory (GLC) report.
