For your consideration are these beautiful turquoise and sterling silver earrings by Mexican artist Francisco Rivera. Very well made with dangling open work balls. One earring bears he Rivera mark and the other is marked Taxco Sterling and the eagle three mark. The eagle dates the earrings between 1945 and 1980. The turquoise has nice color variation ranging from blue to green with matrix throughout.
The earrings measure 1 and 7/8 inches in length. The earrings measure a little over 3/4 inches across - turquoise ball to turquoise ball.
The earrings are in excellent functional condition with all stones secure. I see some lines in one but it may be matrix and it is guaranteed secure.
