Dear Michael, There's a jewelry class at the Academy of Arts Honolulu
that is a combination fabrication and casting class. However, it is
really more for the hobbyist or beginner. If you are a serious
jeweler, the class will at least give you access to tools and
equipment you may not have, as well as a fantastic instructor, Frank
Beaver. The class meets on Thursday nights between 6 and 9 PM from
the end of August through December and then again in January through
May. Class space is extremely limited, so sign up early.
