Pairing black pearls with a heavy gold shackle, jewellery designer Hannah Martin shows her subversive streak with the Double Pearl Shackle bracelet - a piece that is both striking and thought provoking. Fresh from Central St Martins College, Hannah headed to Paris, where she worked as a consultant designer for the likes of Cartier and Givenchy, before returning home to set up her own label in 2005. Since then, her uncompromising vision has gained her famous fans worldwide, including Florence Welch, Rhianna and Daisy Lowe. Handmade in London and limited to 50 pieces, Hannah Martin's Double Pearl Shackle bracelet is a beautiful jewel with a tough, masculine edge. Crafted in 18ct yellow gold and strung by hand with black Akoya pearls, it's another strong visual statement from one of Britain's most creative minds.
