The Gothas sustainable necklaces are part of an artisanal range carefully crafted with 925 Sterling Silver and upcycled PET material. Carol Barreto designed this item to make us re-think how precious what we judge to be waste can be. As opposed to extracting precious stones from the environment, she creatively re-uses and upcycles PET bottles. Handmade in Rio de Janeiro, Brazil. Ethical and sustainable.
