These delightful sterling silver earrings are hallmarked Los Ballesteros. They were in business in Taxco. These earrings are in untouched condition. I have not tried to clean them. They are clips and are in excellent condition with one small dent. They measure about 1" top to bottom and weigh about 7 grams each. Los Ballesteros is a company of excellence. The earrings are beautifully crafted and fully marked.
