This elegant three stone engagement ring features a brilliant oval cut center diamond complemented by two round brilliant side stones. The design offers a timeless trilogy concept with balanced proportions and refined detailing, making it perfect for bridal and fine jewellery collections.

The oval center stone is secured in a classic four-prong setting that enhances its elongated silhouette while allowing maximum light reflection. The two round side diamonds are precisely aligned to create harmony and additional sparkle without overpowering the center stone.

The band has a smooth and slightly tapered profile that flows seamlessly into the setting. The under-gallery structure is carefully engineered to provide durability, stability, and proper light exposure beneath the center stone. The inner shank features a comfortable fit for daily wear.
