Emma Fox is one of my favourite jewellery designers (have a look here at my necklace of two doves with a gold star). Birds, rabbits, fishes and other creatures, are captured in silver with touches of gold. Her pieces are individually handmade, rather than being cast, so each one is slightly different and unique. Emma takes commissions - contact her via her website. Here are some recent pictures of new pieces: fish with charms is perfect for the summer (second pic down), and the horse necklace too (third pic down).
