If you are interested in knowing more about modern silver from Taxco:
“The Los Castillo workshop was founded in Taxco in 1939 by the Castillo brothers (Antonio, Coco, and Chato), along with Antonio's wife Margot van Voorhies Carr, and their cousin Salvador Teran. Los Castillo is the longest enduring workshop in Taxco, and is still in business today with a reputation for the best in both design and craftsmanship.
In the early years of the workshop, Los Castillo was a creative cauldron with many talented designers and maestro silversmiths, that originated techniques inspired by pre-Hispanic artisans that were unique to mid-century Mexican metalworking. Technical genius, Chato Castillo, originated most of these, including metales casados (married metals), onix negro(black onyx inlay), mosaico azteca (stone inlay in silver), and pluma azteca (a sort of stained glass effect from multicolored feathers set in resin and framed in silver), among many others.
Early pieces from the Los Castillo workshop can often be attributed to a particular designer such as Margot or Salvador Teran by the distinctive styles they went on to produce in their own workshops after leaving Los Castillo. Fledgling silver designers Sigi Pineda and Miguel Melendez both worked at Los Castillo, before working for Margot when she opened her own workshop, and then went on to produce their own work a few years later. Both Chato and Coco Castillo remained with the family business, but often marked their pieces with their own marks, and there are strong collector followings for their unique work.”
