18 Karat Yellow Gold Marquise Cut Diamond Engagement Ring

A marquise brilliant-cut diamond commands the center, its elongated outline and crisp, symmetrical points delivering maximum finger coverage and a sleek, contemporary presence. The stone exhibits a modified brilliant facet arrangement—triangular and kite facets radiating from the midline—to emphasize scintillation along the length of the gem. Crafted in solid 18 karat (750) yellow gold, the mount presents a clean, modern profile designed to spotlight the marquise while providing durable, everyday wear. The rich hue of 18k gold enhances the diamond’s brilliance, resulting in a refined engagement ring that balances elegant proportions with precise craftsmanship.
