This elegant Princess Cut Diamond Engagement Ring CAD Design features a modern curved shank paired with a classic square princess-cut center stone. The gently sweeping band adds a contemporary flow to the design while maintaining a timeless and luxurious appearance suitable for premium engagement and bridal jewellery.

The center diamond is secured in a precisely engineered prong setting that provides excellent stone stability and optimal light entry. The curved shank is accented with neatly aligned side diamonds, enhancing brilliance and depth without overpowering the center stone.

Special attention has been given to the under-gallery, prong geometry, and wall thickness to ensure smooth metal flow during casting and accurate stone setting. Clean surfaces and balanced proportions make this design highly reliable for professional jewellery production and finishing.

This CAD model is ideal for both bespoke custom jewellery and scalable manufacturing. It allows easy customization of ring size, stone dimensions, and metal type to match brand or client requirements.
