18 Karat White Gold Marquise Cut Diamond Collar Necklace

A striking collar-length silhouette showcases marquise-cut diamonds set in luminous 18 karat white gold. The elongated, pointed-oval profile of each marquise brilliant maximizes face-up spread and scintillation along the neckline, with the cool white metal emphasizing crisp light return. Crafted in 18k white gold (approximately 75% pure gold), this contemporary 21st-century necklace presents a refined, close-to-the-neck profile for a clean, modern look. The technical pairing of marquise-cut diamonds with a collar format delivers continuous sparkle and a streamlined geometry—elegant, precise, and unmistakably sophisticated.
