Square shapes with black white and brown enamelling, these unusual earrings by Margot de Taxco resemble an optical illusion with smaller and smaller interior squares and are very art deco in style. Measuring 17mm x 7mm, the earrings are screw back and are signed on the top of the attached screw back with the eagle mark 15 hecho in Mexico on one of the earrings and Margot de Taxco no. 546 on the other. It was very difficult to photograph but two of the photos attempt to show this. The enamel work is in excellent condition and these would be a great addition to the necklace, bracelet and/or and brooch set of the matching pattern.
