This bold Tufa Cast Ring has very much Sterling Silver and is very hefty and very solid. The top is 5/8″ wide and tapers down to 1/4″ and the Turquoise is 3/8″ wide. Navajo made.
Tufa casting is similar to sandcast, but the silversmith uses the readily available volcanic rock found in New Mexico and Arizona. The raw volcanic rock is what gives the “textured” appearance where the silversmith carves a design into the rock and pours molten silver into the casting. The volcanic rock is soft and the artist is usually lucky to get one pour from the cast without it breaking. With that said, most tufa cast jewelry is considered one-of-a-kind.
