Three gold necklaces of different lengths (45 cm, 60 cm, 90 cm) are layered on a person wearing a grey shirt. Two have cross pendants, and the longest has a circular pendant with a bar.

Each piece arrives in our colorful jewellery bags made from recycled rice sacks, created together with a social enterprise in Sri Lanka. Durable, reusable, and meant to stick around. see more

Treat gently. Water (especially saltwater), hand cream, soap, perfume and cosmetics can gradually affect the finish. Remove before showering, swimming or exercising. Wipe with a soft cloth after wearing and store in a dry place. Sterling silver loves to be worn. Gold plating stays beautiful the longest with a little extra care.

As each piece is made to order, delivery within the European Union takes approximately 4 weeks.

We ship across Europe with DHL or UPS. Once your order has been dispatched, you will receive a tracking number.
