So, Pam... We seem to have dealt with the spectrolite/labradorite
question, but you inadvertantly sparked another. Irridescent
?hematite? That's new to me. What can you (or anyone) tell me
about it? Thanks! -- Noel
No problem. I love "talking rocks" and am always on the lookout
for really beautiful and unique materials.
Iron oxide occurs in many places and has a widely variable
appearance. You are probably familiar with the hematite (iron oxide)
that takes a nice polish and has a metallic sheen to it.
This iridescent or specular hematite from Arizona formed in plates
and displays an iridescent play of rainbow colors. The surface is
covered with a druse of exceedingly fine crystals. I really enjoy
using this stuff.
Incidentally, it is called Hematite from the Greek word ema (->Hema)
which means blood, as hematite produces a red-colored waste when
