    This ethical jewelry is made from  fully-recycled 925 sterling silver  and set with polished lava stones from the Agung Volcano in Bali.  Each of Kaldera's jewelry is unique, raw and minimal.

    Ondine Cuff Bangle

    • Kaldera conjures up jewellery that is raw, mystical and minimalist  - an homage to the most powerful element on Earth. 

      "With the forces of nature as a source of inspiration, we want to offer a new angle of approach to jewellery, through a very distinctive identity and universe." says the French duo, David and Morgan, who founded Kaldera as personal and artistic explorations as well as an antidote to the corporate world they were part of.

      Using recycled 925 silver painstakingly recovered from discarded electronics , and locally sourced Indonesian lava stones, ethical production is at the heart of each Kaldera piece.    

      Made in the foundry of a traditional Balinese goldsmith,  Kaldera fuses the time-honoured knowledge of silver making and processing methods with a modern and minimal design language, bringing real consistency to each of their products.
