This tufa cast bracelet came from a collection of older Native American jewelry.  We think this bracelet could have been made between the 1950s and 1960s.  The flower petals surround a natural Bisbee turquoise that is a darker and richer color than the photos show.   It has been lightly polished to keep the patina that comes with age.  More about the process of making tufa cast jewelry below. 

Size: 5.5" Long with 1.375" Opening - Turquoise .5" H x .375" W

Tufa Cast: Tufa is a volcanic stone which can be as dense as chalk and has an organic texture. The first thing a jeweler does is examine a piece of tufa for any tiny fractures.  If it looks good, the tufa is cut in half and, if there is a design, it is carved in reverse into the tufa.   There is a pour hole carved into the top and several narrow vents carved into each side.  The two pieces are then bound together tightly and molten silver or gold is poured through the hole at the top.  If there are any microscopic cracks, the tufa explodes when the metal is poured in and the process has to begin again.
