I know the website is no longer around, and FDJ use to have an ad
for them in their catalog of tools, but that stopped a couple years
back. But I see on Lapidary Journals web page that list schools they
are still listed. Only this: Millington - Trenton Jewelry School,
5439 Navy Road (38053).
I understand Trenton use to be a really good school. Then again,
other schools were too at one time.
