This elegant marquise cut engagement ring features a refined split shank structure designed to enhance both brilliance and balance. The elongated marquise center stone is secured in a classic six-prong setting, offering excellent stability while emphasizing its distinctive pointed silhouette.

The split shank design gracefully separates as it approaches the center stone, creating a light and sophisticated profile. A row of pave-set diamonds runs along the inner channel of the band, adding subtle sparkle that enhances the ring’s brilliance from multiple angles.

The elevated gallery allows generous light exposure beneath the center stone, improving fire and scintillation while maintaining structural strength. The band is smoothly contoured for comfortable daily wear, making the design both practical and luxurious.

This CAD model is professionally engineered for jewellery manufacturing. Prong thickness, stone seats, pave spacing, and metal weight are carefully optimized for clean casting, precise stone setting, and smooth finishing.

The model can be customized for different center stone dimensions and is suitable for production in yellow gold, white gold, rose gold, or platinum. A perfect addition to bridal collections seeking a modern split shank style with timeless marquise elegance.
