This elegant marquise diamond engagement ring 3D model is designed with a luxurious double band structure and detailed side cluster setting. The centerpiece features a stunning marquise-cut stone secured with refined prongs, elevated to enhance brilliance and light reflection. Surrounding the center stone, carefully arranged marquise and round accent stones create a floral-inspired cluster that adds depth, sparkle, and premium appeal.

The double shank band provides both structural strength and a modern high-end aesthetic, making this design ideal for engagement collections, bridal jewellery lines, or custom luxury projects. The model is crafted with clean geometry, precise stone settings, and production-ready detailing suitable for casting and manufacturing.

This ring is perfect for jewellery designers, manufacturers, retailers, and rendering artists who require a high-quality, accurate CAD model for professional use. The design is optimized for realistic rendering and smooth finishing after casting.

The model is available in multiple metal variations including yellow gold, white gold, and rose gold presentation renders.
