3.65 Oval Blue Sapphire Engagement Ring 18k

This 18 karat white gold three-stone ring centers a 3.65 carat oval cut blue sapphire flanked by two half-moon diamonds totaling .66 carats (.33 carats each). The oval cut sapphire shows a deep blue color and has an elongated shape that covers more finger space than a round stone of the same carat weight. Half-moon diamonds are shaped like semicircles and fit snugly against the curved sides of the oval sapphire, creating a cohesive flow across the ring's face.

The white gold setting provides a neutral backdrop that lets the blue sapphire stand out without competing for attention. The 2mm band width makes this comfortable for daily wear while keeping the focus on the three main stones.
