Margot de Taxco is the undeniable queen of zodiac jewelry in my opinion, at least within the field of vintage Mexican silver. Her astrological pendants are unsurpassable in their sculptural qualities and here the treat is amplified because the Aquarius charm is paired with a hefty Carlos Castillo chain of the same period. Exceptional workmanship, great weight and patina to die for make for a stunning necklace that is 19 1/2" long. The pendant itself ahs a diameter of 1 5/8" and adds a 2 1/8" drop to the chain. The necklace weighs a combined 49.7 grams and both pieces are fully and appropriately signed (the CC for Carlos Castillo is there but in the photo partially concealed by the fold of the chain link). Dating in the 1950s-60s and in excellent vintage condition.
