Seine 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.
Center Stone Size
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.

The Seine engagement ring is slender, yet sparkles from every angle. The Nexus Diamond™ alternative center stone is fiery and the high-profile setting is somewhat eased by the sloping cathedral shoulders. The band shimmers with pavé set accent stones along the rounded top and the arched side beneath the setting. It is a stunning selection for the woman who loves understated glamour.
We are continually improving and updating our pieces to ensure our lifelong quality promise. As of summer, 2019, the Seine engagement ring was changed to include more stone options. The ring is now featured in Round, Cushion, Princess, Oval, Emerald, Radiant, Pear and Marquise Nexus Diamond™ alternative. For more detailed information, please contact Customer Care.
