There is a very good school in Richmond, VA called the Jewelry
Design Institute run by Allison Young, who has about 25 years
13354 Midlothian Turnpike Suite 202
PO Box 475
Midlothian, VA 232113
I took a class there and it was really good – she’s a great
teacher and you do lots of hands on lab work and learn a lot.
They offer one week classes in: Jewerly Design, J Repair, Stone
Setting, Wax Modeling and Casting.
They’ll give you help with finding a hotel and have a shuttle
service (or, at least, they did when I was there) and will pick
you up from the train station/airport and from your hotel each
day for class.
JDI runs ads in Lap Journal and such, so if my info. is out of
date, you can find it there.
I highly recommend the Jewelry Design Institute. Someone else
posted why not go to California, and I agree that would be
great, but not always possible.
