The Orion 18K Yellow Gold: Multi-Stone Lab-Grown Diamond Band

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

The Orion 18K Yellow Gold: Multi-Stone Lab-Grown Diamond Band

Celestial. Dazzling. Powerfully Unique.
The Orion is a high-impact diamond band featuring a sequence of oval, pear, and heart-shaped lab-grown diamonds, each meticulously set to create a constellation of brilliance. Its sculptural design captures light from every angle, making it a statement that can stand alone or stack effortlessly.

Crafted in solid 18K gold or platinum, The Orion balances show-stopping presence with a comfortable, wearable fit. The open side-gallery design maximises light flow, enhancing the fire and sparkle of every stone.

Features:

  • Lab-grown diamonds in alternating oval, pear, and heart shapes
  • Prong-set for maximum brilliance and security
  • Available in 18K rose gold, yellow gold, white gold, or platinum
  • Total carat weight varies by size (approx. 1.0–5.0 carats)
  • Internally flawless and IGI certified
  • Complimentary custom engraving included

Customize Your Orion:

  • Select your ring size for a perfect fit
  • Choose your metal: 18K gold (rose, yellow, white) or platinum
  • Add a personal engraving at no additional cost
  • Handcrafted for you, shipped worldwide
