Caldera

Each John Miller Design piece is hand-wrought in our Yallingup atelier using old-world metalsmithing techniques. Designed for decades of wear, your jewellery will develop a natural patina unique to you. With thoughtful care, it will remain part of your story for years to come.

1. Remove before harsh exposure

Take off your jewellery before swimming, gardening, or heavy manual work. Limit prolonged exposure to water and household chemicals to preserve the surface finish.

2. Store separately

When not being worn, store your piece in a soft pouch or lined jewellery box to prevent scratching.

3. Clean gently

Polish with a soft cloth for regular maintenance. For a deeper clean, wash in warm water with mild soap, rinse thoroughly, and dry completely.
