Eterna oval lab diamond bridal sets create a continuous composition from two or three rings, pairing the balanced center shape with fitted pavé, scalloped or accent bands. Each solid gold set is made to order with applicable IGI documentation and process photos preserving its final arrangement. Matching stud earrings and necklaces will continue the series beyond the ring stack.
I was nervous about buying a ring online but it seemed like it would be a wild goose chase trying to find an elongated hexagon moissanite engagement ring (which is what my now fiance wanted) so I took a chance with Brilliant Carats and I'm glad I did. The ring is high quality and the price can't be beat. I will be shopping with them again for a wedding band.

Two or Three Rings, One Continuity
Eterna uses multiple rings to create a continuous visual rhythm around the oval center. Every band is selected to support the complete arrangement rather than compete for attention.

Frequently Asked Questions
What defines an Eterna bridal set?
Eterna is a coordinated two- or three-ring stack built around an oval lab diamond. Its matching bands repeat and continue the oval’s balanced curves, creating a composition intended to feel complete from every angle.
Should I choose a two-piece or three-piece Eterna set?
A two-piece set combines the engagement ring with one coordinating wedding band for a refined layered look. A three-piece set frames the engagement ring from both sides for greater symmetry and presence.
Can Eterna rings be worn individually?
Yes. Each ring can be worn separately, while the fitted proportions allow the pieces to sit together as the complete Eterna composition.
How is an Eterna set different from a Celeste set?
Eterna centers on the balanced symmetry and continuous curves of an oval diamond. Celeste follows the directional teardrop outline of a pear cut and uses more pointed, constellation-like arrangements.
Are Eterna lab-grown diamonds real and documented?
Yes. Lab-grown diamonds have essentially the same chemical, physical and optical properties as natural diamonds. Applicable IGI documentation may cover a diamond or the completed jewelry, depending on the piece.
What is included with a made-to-order Eterna set?
Most Eterna sets require 7–10 working days to make. Process photos document the individual rings and their final alignment before delivery.

Balanced Around the Oval
Pavé, scalloped and accent-diamond bands follow the oval’s symmetry and graceful length. Two-piece sets feel refined, while three-piece combinations create a more formal framed effect.
