Collectors of Southwestern jewelry all over the world are familiar with the unique delights of tufa cast jewelry. The Diné or Navajo people of the American Southwest are particularly well-known for their astonishing sand and tufa cast pieces.

The organic look and feel of finished tufa cast jewelry is evocative of the generations of silversmiths who have handed down the practical techniques, creative fire, and the essence of the land and people as one.

Creating tufa cast jewelry is an intense physical process. Finished products are the result of creative excellence and sincere mastery of diverse skills, Diné silversmiths are recognized around the globe for this high level of craftsmanship and artistry, and we are delighted to answer some common questions about this renowned Native American jewelry from the Southwest.

The formation of tufa

Compressed volcanic ash forms the porous tufa rock found on the Navajo reservation in New Mexico. Artisans collect the tufa and use it as the carving and mold material for creating finished jewelry. Tufa has a porous nature which is responsible for the signature look and texture associated with tufa cast jewelry.

The texture of the earth, the pressures exerted on the mold, the fire, and the cooling all combine to leave a distinctive, unique surface that makes such a striking centerpiece of Native American necklaces and other tufa cast jewelry.

preparing the Tufa

Artists begin the process by preparing the tufa stone. The stone is cut and cleaned, and the sides that will create the mold are rubbed vigorously together until they are flush. The finished design is drawn and then carved directly into the tufa, creating a perfect mold for the finished piece. The artist will calculate the carving to include a vent and sprue hole where the molten silver will be poured.

The tufa stone has to be carbonized before molten silver can be poured into it. In the video below, you will see Philander Begay complete this process with a gas torch. The two sides of the stone are sooted and bound, ready to receive the metal.

Creating the Tufa Jewelry

Melting and pouring the silver is an exciting and dangerous part of the process. Heated to its liquid state, the exact amount of needed molten sterling silver is carefully poured into a mold.

Patient waiting for the mold to cool ensues. Once cooled, the mold is opened and the excess tufa is gently cleared away, as well as the extra silver from the sprue hole where the metal entered the mold.

The work to complete the jewelry begins and includes all of the skills necessary to fulfill the original vision. Depending on the design, sawing, sanding, setting stones, oxidizing, overlay work, inlay stones or bezels for stones are created, polishing cleaning and buffing will all be part of the silversmithing process. All of these processes will be carried out with great care not to disturb the earthy texture of the tufa where it is part of the finished piece.

The original tufa mold is often used only once, making many tufa cast items one-of-a-kind collectibles.
