For your consideration are these large and pretty Mexican Sterling silver earrings. The bottoms are purple and I believe it is sugilite. They are puffed with decorative squiggles on each side. The marks are TM-107 Mexico 925. This makes them from Taxco and after 1980 but they have nice patina and age.
The wear length - from the top of the wire to the bottom of the drop - measures 2 inches. They measure 1 and 3/8 inches across.
They are in excellent condition. No damge.
