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.

Product Details

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.

  • Center stone is available in a variety of carat weights; choose yours from the menu above.
  • Set with the Nexus Diamond™ alternative: a lab created diamond simulant that is chemically distinct but virtually indistinguishable from a perfect diamond. Each stone is guaranteed for life and should not chip, crack or discolor or we will replace it for free, no questions asked, for life.
  • Stones shown on the model's hand are for reference only. Actual carat weight availability may vary by ring style.
  • Complete this look with the Seine Wedding Band.
  • Order additional services like a personal appraisal for $50 or an engraving for $25. Contact customer service for details at 1.800.509.4990
