Call me picky, but wouldn't a rich, saturated red beryl be
considered bixbite, rather than a variant of morganite?
In the case of this new Madagascan beryl it is very different from
red beryl (bixbite) which is found exclusively in Utah. Explaining
color in words is difficult but I'll try. I will also describe
further the other differences that I saw:
a.. The rich saturated magenta raspberry red of the new material is
not at all like the red beryls from Utah. It is much more fuschia or
magenta. Not a pastel color either. I have seen a couple of XF
morganites which came out of Madagascar pre 1985 which looked like
the very best pink imperial topazes from Ouro Preto Brazil. This new
material is similar to that color except many times more saturated.
b.. The size of the new material was larger than any red beryl ever
found in Utah by at least 10x. Some of the pieces I saw were as large
as a walnut in the rough. Approximately 50 grams would be my guess.
c.. The crystalization was totally different from hexagonal prisms
of the Utah red beryl with the elongated C-Axis. The new Madagascan
material that I saw was composed of oscillating stacks of tabular
hexagonal crystals with a shorter C-Axis predominantly associated
with moragnite. This shorter C-Axis crystals were bound together
with their center lines offset (oscillating) to look like a stack of
flat hexagonal blocks stacked unevenly along a wavey central axis.
That is about as well as I can explain them from my brief contact
with the new beryl. Seeing this new material would make it
immediately obvious (to anybody) that it is not "red Beryl" in the
classic sense. It is something entirely new and never seen before in
the mainstream gem circles. Stay tuned, I'm sure that it will be
written about in the publications.
