18 Karat White Gold Marquise Cut Diamond Engagement Ring

A marquise-cut diamond takes center stage, defined by its elongated, double-pointed silhouette and brilliant-style faceting that emphasizes scintillation along the stone’s length. The marquise profile offers impressive finger coverage and a sleek, contemporary look ideal for an engagement ring. The diamond is set in solid 18 karat white gold (approximately 75% pure gold alloyed for strength and a bright, neutral tone), complementing the stone’s crisp brilliance with a clean, modern aesthetic. A contemporary 21st-century design, it prioritizes streamlined geometry to showcase the marquise’s distinctive outline and luminous facet arrangement.
