With a total weight of approximately 11.00 carats for the diamonds and 10.80 carats for the rubies, these earrings reflect meticulous craftsmanship from Spain's late 20th century jewelry scene. Measuring at one inch in length and three-quarters of an inch in width, they are signed by Yanes and bear maker’s marks as well as assay marks indicating their authenticity.
