18 Karat Yellow Gold Rainbow Sapphire Open Heart Necklace

A vivid sweep of rainbow-hued sapphires traces an elegant open-heart silhouette crafted in solid 18 karat (75% pure) yellow gold. The clean, openwork design maximizes color visibility, allowing each sapphire’s tone to stand out against the warm luster of high-karat gold for a crisp, contemporary profile with lasting substance. Materials: 18k yellow gold framework with multi-color sapphire accents. Stone details: sapphire, color—multi (rainbow spectrum); cut—unspecified; clarity—unspecified; total carat weight and stone count—unspecified. A refined, balanced heart outline and sapphire-set detailing make this a striking everyday statement with fine-jewelry construction.
