This elegant engagement ring features a striking marquise cut center diamond secured in a refined four-prong setting. The elongated silhouette of the marquise shape creates a flattering, finger-lengthening effect while maximizing brilliance and surface appearance.

A delicate hidden halo of micro pave diamonds is placed beneath the center stone, adding subtle sparkle visible from the side profile. This refined detail enhances brilliance without interrupting the clean and classic top view of the solitaire design.

The smooth, polished shank maintains a minimalist and timeless aesthetic, allowing the dramatic marquise cut to remain the focal point. The gallery structure is engineered for durability and proper light exposure, ensuring optimal brilliance from the center diamond. Prongs are proportioned for secure stone setting while preserving a sleek and balanced look.

This CAD model is designed specifically for professional jewellery manufacturing, featuring accurate stone seats, proper wall thickness, and clean geometry for smooth casting and finishing. Suitable for production in yellow gold, white gold, rose gold, or platinum.
