Tufa Cast Sterling Silver
100% solid silver won't tarnish but it is too soft to use for making jewelry - it could easily be scratched, dented and bent. Sterling silver has a small amount of one or more other metals usually copper, added to the silver. To be called sterling silver, the alloy must contain at least 92.5% pure silver. Sterling silver alloy is harder than pure silver but the added metals also can cause discoloration or tarnish.
What does Tufa Cast mean?
Tufa cast, or sand cast, items are made using a procedure developed by Navajo silversmiths in the mid 1800s. It is a labor-intensive process that involves many steps. First, the artisan carves the design of the item being cast into the flat surface of a stone. Stones typically used are tuff, a porous volcanic ash material; tufa, a porous limestone that forms near hot springs; and sandstone, which is somewhat harder. Next, another smooth flat stone is placed against the carved half of the mold. The halves are fastened together and a sprue hole is carved into one end. Molten silver is poured into the mold through the sprue hole. Once the silver cools, the halves are separated and the item is taken out and finished. Bracelets are poured flat and then shaped.

Turquoise is associated with the sky,
and bringing sky energy to earth. It is known as a master healer stone as it is
believed to help speed the healing process. It is also thought that turquoise
can help promote honest and clear communication from the heart.
Why isn't this item called Native American?
The US Department of the Interior Indian Arts and Crafts Act of 1990 and its recent Amendments require that items described as Native American or Indian be made by an enrolled member of a federally recognized tribe. Furthermore, government regulations suggest that all attributions include the Native American Indian's name, tribe and federal tribal enrollment number. Because it is impossible to identify the artist for many vintage items, even if they are authentic Indian made items, we cannot and will not use the words Native American or Indian in association with such pieces.
