Liza Todd-Tivey is a well-respected sculptor renowned for her ability to render horses in a startlingly realistic manner. She has a small number of pieces of jewellery on her site, including this wonderful double horse brooch, called Hearts in Tandem. Using matte faux gold and pearl drops, the finish reminds me of Elizabeth Gage’s work. The piece was done for Avon as part of the Elizabeth Taylor line.
