Well this is a lovely lead in for me to plug my favorite Tourmaline
source,me. I have a huge stock of all grades of Tourmaline roughs,from
numerous mines. In fact,my company was the largest buyer of Tourmaline
in Brazil for an 8 year period,throughout the largest single pocket
of Tourmaline every found in the history of Brazil,Morro Reddondo
mine.It ceased when Morro Reddondo exhausted at the same time as the
huge find in Nigeria hit the market.I have a super lot of that too.In
fact,most of my materials only I have as I made a point to buy entire
pockets or productions.The Tourmaline is pictured and described in
several locations on my website,faceting,cabachon,collection,even
some bargin collection materials in close out.The URL to my site in
my sig.below. For those of you interested,and to justify this
shameless advertisement,a report I have written,and republished to my
pride and delight on Ganoksin site of the amazing strike of Tourmaline
at Morro Reddondo,upper N.W.in the State of Minas Gerias,Brazil is at
this URL http://www.LICCINI.com/Mining/MiningIndex.htm At that same URL
you can research all the occurances of Tourmaline in Brazil,in a rare,
out of print volume(70MB) “MINERAIS do BRAZIL” And also at that URL
the now discontinued publications of the defunct U.S.Bureau of Mines
“AN OVERVIEW OF GEMSTONE PRODUCTION IN THE UNITED STATES” and
“DIRECTORY OF THE PRINCIPAL U.S.GEMSTONE PRODUCERS IN 1993” Mark
