Asta Marquise Engagement Ring
The Asta Marquise Solitaire Ring combines timeless elegance with a distinctive silhouette. A marquise-cut lab-grown diamond takes centre stage, its elongated shape and pointed ends highlighted by a refined prong setting. A smooth, polished 18K gold band completes the design, allowing the diamond’s brilliance to shine.
A beautiful choice for an engagement or a personal milestone, the Asta ring can be customised with a diamond size of your choice.
