This oval diamond three stone engagement ring is designed with graceful curves and refined detailing, featuring a brilliant oval-cut center stone accented by two round side diamonds. The center diamond is secured in a classic four-prong setting that maximizes light exposure while ensuring strong structural support.

The split-style upper shank gently flows toward the center setting, creating a soft and elegant profile that enhances the brilliance of the oval stone. The two round side diamonds are positioned to complement the center stone perfectly, forming a balanced three-stone composition symbolizing past, present, and future.

An open gallery beneath the center stone allows proper light entry, enhancing sparkle and depth. The smooth and polished band provides durability and long-term comfort, while the inner shank is designed with a comfort-fit profile for everyday wear.

This CAD model is professionally developed with accurate stone seats, clean prong alignment, optimized wall thickness, and casting-ready geometry. The structure is designed to minimize finishing corrections and ensure efficient production workflow.

Ideal for bridal collections, engagement jewellery lines, custom designers, and jewellery manufacturers seeking a refined oval three-stone ring ready for manufacturing.
