The Sfera sustainable, handmade earring is part of an artisanal collection carefully crafted with 925 Sterling Silver and upcycled PET material. Carol Barreto designed this collection with the purpose of making 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. Ethically made. Sustainable.
