Behind the piece

The Orion Multi-Stone Diamond Band – Lab-Grown | 18K Gold or Platinum

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

The Orion is a diamond band set with an alternating run of oval, pear and heart-shaped lab-grown diamonds, so it catches light from every direction. The open gallery underneath keeps it light on the finger and lets the stones sparkle, and it wears just as well stacked as it does on its own. Made by hand to order in solid 18K gold or platinum.

Specifications

  • Diamond: Lab-grown, high clarity, IGI certified
  • Shape: Oval, pear and heart cuts
  • Setting: Prong-set band
  • Metal: 18K yellow, white or rose gold, or platinum
  • Carat: 1ct to 5ct total, chosen at checkout
  • Engraving: Complimentary
  • Made to order: Handcrafted to order, around six weeks
  • Designed in Australia

Do you ship internationally?

Yes. We ship worldwide using trusted, insured courier partners.

All duties and taxes will be shown at checkout where applicable.

What is your return policy?

Please refer to our policy here.

Craftsmanship & Materials
What materials do you use?

No plating. No mixed metals. No mined diamonds.

Where are your pieces made?

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