Elongated Cushion Lab Diamond Eternity Band

$5,460.00

The elongated cushion cut takes everything that makes a cushion desirable, the soft corners, the warm brilliant-cut flash, and stretches it into a silhouette that covers more finger, reads longer, and allows for significantly higher total carat weights than a square cushion in the same band.

Each diamond is set with its long axis running around the circumference of the band, creating a continuous ribbon of light that flows like water around your finger. The result is one of the most visually impressive eternity bands available, dramatic total diamond weight, distinctive modern shape, unmistakable from every angle.

Every diamond is a lab grown elongated cushion cut. DEF color, colorless. VS clarity, eye-clean. Ideal Cut. The finished band comes with an IGI Certificate documenting the total carat weight, diamond quality, and metal specifications of the complete piece.

Available in total carat weights from approximately 4.5ct to over 11ct depending on diamond size and ring size selected. Total weight varies by ring size as larger sizes require additional stones to complete the full band.

Made entirely to order. Cannot be resized. All sales final.

Because diamonds run continuously around the entire band, resizing is not possible without damaging the setting. Every band is custom manufactured to your exact ring size. Please confirm your size carefully before ordering. If unsure, visit a local jeweler for professional sizing.

Allow 8-12 business days from order to shipment.

Questions, Answered

Before You Decide

Can an eternity band be resized?

Not in the traditional way. Because diamonds run the full circumference of the band, there is no plain metal to cut and rejoin. That makes getting the size right the first time important: start with our ring sizing guide, and if you are between sizes, talk to a jeweler before you order. Guidance is always complimentary.

When will my ring ship?

This piece is made to order in our Los Angeles atelier. Allow 10 business days from order to shipment, then fully insured FedEx Priority Overnight delivery, signature required.

Is a lab-grown diamond a real diamond?

Yes. A lab-grown diamond is chemically, physically, and optically identical to a natural diamond: the same crystal, the same hardness, the same brilliance. It is how a ring like this carries this much diamond at this price.
