As far as Jewelry/Metals shows go I'd check out the show at the
Mobilia Gallery in Cambridge Mass. The current work is from
California Metalsmith Marilyn da Silva, and British artist Kevin
Coates. It's really worth checking out!
Also if you have time visit other museums in Boston such as the:
I know my undergrad school, Massachusetts College of Art has some
shows up and I'm sure other Colleges in Boston might as well.
There are also small galleries along Newbury Street (Boston) such as
the Society of Arts and Crafts, and there are some Jewelers located
in South End and Fort Point portion of Boston.
Come to think of it October is a big month for many artists having
their open studios. So if you're there during that time go check it
phew Hope this was helpful...and oh Have fun!
