This is one of the fabulous David-Anderson sterling silver Zodiac pendants from the 1960s. This measures 7/8" from point to point on its hexagonal shape. I have 7 of the small round charms, and 3 of the larger hexagonal pendants, all of which I'm posting today.
From the well-known Norwegian silversmith David Andersen, this is marked on the back "D-A Norway Sterling 925S". It is in excellent condition, and ready to be placed on your necklace. It can also be used as a charm on a charm bracelet, but please remember it is large.
This one is Aries, the Ram, which represents the astrology sign from March 21-April 19th. I have two of these. The others I am posting are Capricorn, Aquarius, Virgo, Libra, and Cancer. I have duplicates of some of these.
