18 Karat White Gold Madagascar No Heat Purple Sapphire and Diamond Ring

Unheated Madagascar purple sapphire takes center stage in this contemporary 18k white gold ring, showcasing a cushion-cut corundum with richly saturated purple color. The natural, no-heat status emphasizes its rarity and collector appeal, while diamond accents provide precise, high-scintillation contrast against the cool-toned metal. Crafted in solid 18 karat white gold (approximately 75% pure gold), the mounting presents clean, modern lines that prioritize the sapphire’s cushion profile and balanced presentation. The combination of an unheated origin stone, diamond detailing, and a contemporary 21st-century design delivers a refined statement with enduring technical integrity—finished with the crisp brilliance of white gold and the jewel-toned depth of purple sapphire.
