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
Choose between the Nexus Diamond™ alternative and Moissanite.
The Nexus Diamond™
Patented lab created diamond simulant that accurately replicates the look, wear, and feel of a perfect diamond. Indistinguishable from diamond to the naked eye.
Popular and highly durable lab created gemstone with more fire and brilliance than a diamond. Beautiful and eye-catching.
Nexus Diamond Alternative
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.
Ship Date: 7/15, If ordered by 2PM (CT).
The Seine engagement ring is slender, yet sparkles from every angle. Either the Nexus Diamond™ alternative or Moissanite 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.
