Una Diamond Gift Card

$50.00 AUD

Behind the piece

Una Diamond Gift Card

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

Celebrate life's special moments with the Una Diamond Gift Card, a way to give the gift of a ring someone chooses for themselves. Good for engagements, anniversaries, birthdays, or no occasion at all, it lets them create their own lab-grown diamond ring.

With Una Diamond, they'll get:

  • Origin: grown in a lab, not dug out of the ground.
  • Customisation: a bespoke design journey, from CAD drawings to a finished piece, built around what they want.
  • Transparency: centre stones of one carat and up are IGI certified, and cut, colour, clarity and carat come from that certificate. IGI sets that threshold, not us.

How it works:

  1. Choose the gift card amount.
  2. Your recipient redeems it toward their ring.
  3. They work with Una Diamond to design a piece that suits them.

Gift card valid for all Una Diamond products and services. Non-refundable. Valid for 2 years from purchase.

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