Who started it? This is not only a design collaboration between husband and wife Dara Gerson and Ashley Lowengrub, it's a statement against the harmful social and environmental effects of mining - something the couple's career in the jewellery industry had brought home to them. Gerson and Lowengrub turned their backs on traditional industry practices and created a fair trade, eco-sustainable business. All Alkemie jewellery is handmade from reclaimed metal in downtown Los Angeles. Why we love it: the pieces have a beautifully raw feel to them. The designs reflect the inspiration drawn from the couple's love of nature, culture and global eco-awareness. What we'd pick: the wing earrings (above right; HK$2,690) are a true statement piece and a sure way to make you stand out while the alligator bangle (above left; HK$3,300) would give a simple outfit a glamorous and fun twist.
