This is the sweetest little leopard with a crown of 6 pearls, cabochon emerald eyes and 4 small diamond collar. The spots are indented and painted with enamel paint and the tail circles down in a great swirl. The back of the tail is marked TECLA 14K and I have tested it. This is a very good quality piece of jewelry I could not find any information on TECLA but I will keep looking. The pin measures about 2 inches by 1/2 inch and weighs 7 grams. Please feel free to ask questions and thanks for looking.
