Behind the piece

The Nova: 18K Yellow Gold Pear & Emerald-Cut Lab-Grown Diamond Toi et Moi Ring

Every Una ring begins with a clear point of view and a commitment to craft. Yours is no exception.

The Nova: Pear & Emerald-Cut Lab-Grown Diamond Toi et Moi Ring

Modern romance. Perfect balance. 
The Nova is a contemporary take on the iconic Toi et Moi (“you and me”) design, pairing a pear-cut and an emerald-cut lab-grown diamond in a fluid, bypass setting. Each stone represents two distinct yet complementary souls, joined in harmony.

Crafted in solid 18K gold or platinum, The Nova’s open design curves elegantly around the finger, creating a striking silhouette from every angle. It’s bold enough to wear solo, yet versatile enough to pair with bands for a personalised stack.

Features:

  • Pear-cut and emerald-cut lab-grown diamonds in a bypass Toi et Moi setting
  • Modern open design for a sculptural profile
  • Available in 18K rose gold, yellow gold, white gold, or platinum
  • Carat range: 1.0–4.5 carats total weight
  • Internally flawless and IGI certified
  • Complimentary custom engraving included

Customize Your Nova:

  • Choose your diamond sizes: 1.5–4.5 carats combined
  • Select your metal: 18K gold (rose, yellow, white) or platinum
  • Add your personal engraving at no additional cost
  • Handcrafted for you, shipped worldwide

Why Nova?

  • Named for the brightest bursts of light in the night sky, The Nova is both a love story and a style statement. Perfect for engagements, anniversaries, or simply as a symbol of two worlds colliding beautifully.
  • Design your Nova today, made for brilliance, built to last.
    Sustainable. Sculptural. Made for you.

What is your return policy?

Please refer to our policy here.

Craftsmanship & Materials
What materials do you use?

First marriage didn't work out, but I'm pretty sure it's because it wasn't an Una Diamond!
