Description

This is more than just a piece of jewellery; it’s a collaboration. A chance to create your own, one-of-a-kind piece of magic. The Australian opal is no ordinary gemstone; each stone holds its own universe of colour and light. We have hand-selected a collection of the most beautiful freeform opals, and now the choice is yours.

Every opal is a tiny painting by nature, with a unique play-of-colour that dances in the light. No two stones are the same. After you place your order, we will contact you, and you get to choose the stone that calls to you from our curated selection—the one that tells your story.

A piece like this is a hero all on its own. Wear your opal ring or pendant as a daily, personal talisman. It’s a conversation starter that reflects your unique story and style.

How to order

The process is simple and personal:

  1. Place your order for this product listing.
  2. On request we can email you photos of the opals we currently have available.
  3. You choose the stone you love most.
  4. You let us know if you'd like it made into a ring (don't forget your size!) or a pendant.
  5. We get to work in our atelier to create your unique, handmade piece.
