Single Knot Marquise Diamond Ring CAD Design | Marquise Stone Knot Ring 3D Jewelry Model

This elegant single knot marquise diamond ring CAD design features a graceful intertwined structure that symbolizes unity and timeless elegance. The centerpiece of the ring is a marquise-cut diamond, positioned horizontally and secured with delicate prongs.

The ring band flows into a smooth knot-inspired structure, where the metal curves and overlaps to create a refined twisted appearance. This flowing knot design wraps around the center marquise stone, highlighting its elongated brilliance and creating a balanced, modern silhouette.

Small accent diamonds may be set along parts of the knot structure, adding subtle sparkle while maintaining the clean architectural look of the ring. The band gradually tapers toward the back to ensure comfort and elegant proportions.
