Jewelry is going green: conservationists and designers are reshaping the industry with sustainable practices. In Germany, Wolfgang Degelmann breeds endangered river mussels to restore habitats. In Fiji, Justin Hunter’s pearl farm protects black‑lip oysters while engaging locals in marine conservation. In Austria, the Hofer twins collect crystals under strict ecological limits. And designer Helge Maren Hauptmann turns to lab‑grown diamonds — indistinguishable from mined ones but cheaper and less harmful. Together, these efforts show how guilt‑free gems can balance beauty with responsibility.
