Timeless Marquise Cut Engagement Ring
Many of our engagement rings and fine jewelry pieces are available in yellow gold, white gold and rose gold. All of our Sage Collection rings are created using 10k gold. To upgrade your piece to 18k gold, platinum or palladium please call our customer service line at (800) 509-4990.
Nexus Diamond™ alternatives, like natural diamonds, are measured by carat weight. Unlike natural diamonds, the Nexus Diamond™ alternative costs up to 80% less than a mined diamond of comparable quality and weight. For reference, a 1.03 carat round brilliant stone is about the size of a pencil eraser.
Center Stone Size
Ring size measurements refer to the inside diameter of a ring. Your ring size can be determined at home using a piece of string or a thin piece of paper, or you can visit a jeweler to be professionally sized. Read more here. Our artisans offer one complimentary resizing within one year of purchase date for most standard ring styles sizes 4-10.
Save money by purchasing a matching wedding band. This engagement ring has an accompanying band that's perfectly the same in design, ring size and metal type. If you'd like a different configuration, please contact us at (800) 509-4990.
This twist on a three-stone ring is simultaneously modern yet true to its traditions. The Marquise cut Nexus Diamond alternative is flanked by two Trillion cut side stones. The curved lines of the Trillion cut stones mirror the curved lines and pointed corners of the Marqusie cut, creating a cohesive yet visually balanced piece. This ring features a lower basket settings and subtle cathedral shoulders for comfort. It is a piece that draws inspiration from the past, honors the present trends, yet has simplicity to remain beautiful into the future.
We are continually improving and updating our pieces to ensure our lifelong quality promise. As of fall 2018, the Timeless ring design was updated to feature Trillion cut side stones, more visually subtle prongs, and a more delicate overall design. In addition, the Marquise ring has a new matching band.
