How it works

Got questions? Our Made-to-Order FAQ covers everything you need to know about production times, shipping, and returns.

For our artisans in Indonesia, jewellery is more than metal—it’s craft, ritual, and story. As Ramadan nears, they pause to honour family, reflection, and tradition.

This means our Made-to-Order production will haveanextended processing time. Production resumes once our artisans return. This means anyorders placed between now and the 15th April will be shipped early May.

Handcrafted in 3-4 weeks, with an additional week for delivery. Engraving adds 2 extra days. Enjoy the benefits of intentional craftsmanship—no mass production, only quality and exclusivity.

As each piece is unique, returns are eligible for store credit only, excluding earrings, studs, sleepers, and engraved pieces. If you’ve made a mistake with your order, please contact customer support within 24 hours of purchasing so we can assist with any changes. If we’re not notified within this timeframe, you’ll need to wait until your order is received to arrange any adjustments.
