I think I have true tree coral. I bought it from a good dealer (Bill Gangi
I think his name was) at the ACC show in Baltimore.. It was harveted in
Italy in the 1970's. This form happens to fit the seahorse casting I have.

I'll try the acetone clean-up, burr abrading and epoxy gluing.

By the way, Connaissance Des Arts had a nice article on aged red coral a few
months ago. That gave me the idea. They have a nice thing on Lalique now.

Seems like a lot, if not most, of the :"red coral" I see strung into
various
beads (some of sizes I'd never expect to find in a true gem quality coral)
at
the gem shows, especially the retail level ones that seem to have an awful
lot
of beads and junk, are not coral at all, but dealers grudgingly, if at
all,
elaborate on "coral" by explaining that it's dyed "sea bamboo". Now, I'm
not
sure just what sort of plant or animal "sea bamboo" really is, but it's
not,
I'm told, a true coral. I was told the stuff grows fairly rapidly, and
it
does seem to work easily, and if you're not too picky about
identification,
seems attractive enough with a sometimes interesting texture. I just wish
the
stuff was marketed a bit more honestly, not trying to imply that it's a
true gem
coral, or that the color is naturally red...

I wonder if, Silverstall", your "sponge" coral is related to this stuff
called
"sea bamboo"? there seems, from your photos, a visual resemblance...
