A couple weeks back a remember seeing that someone was looking
for dichroic glass cabs. I don’t remember who was looking, but I
did find someone in California who does them. Paula Radke has a
website at “home.earthlink.net/~dichro” which shows some of what
she has available, and, although it does not list cabochons, I’ve
spoken with her and she said that she does have cabs available
also in various sizes and shapes. If you are interested, you can
e-mail her at firstname.lastname@example.org.
Hope this helps. I know that I’ve been looking for dichroic
glass cabs myself for a while with little success until now.
