Elsa Peretti for Tiffany
Elsa Peretti had just joined Tiffany the previous year, and the company is already featuring her designs in full page advertisements in 1975. Interesting to note that the ad states these earrings are for pierced ears, which were becoming very popular with younger women. But Tiffany placates it's traditional buyers by pointing out that you can also wear this pierced earring as a pin.
