brownish red, terminated tourmaline from the Malchan pegmatite field in
Eastern Siberia. There is no damage; all the edges are sharp and the
faces intact. The
Malchan deposit is actually a fairly recent discovery, having been
discovered southeast of Lake Baikal (near the Mongolian border) in 1980.
The locality has been producing in small amounts since, though on a
scale far smaller than either the Brazilian or Afghan tourmaline
deposits. I will also add that the "warmer" colored
tourmalines (reds, yellows, oranges) are known from fewer deposits than
the greens and blues (which account for the bulk of the Afghan/Brazilian
production.) To my knowledge the main producers of these colors are
currently Malchan (where this one is from), and the various pegmatites
in Madagascar and Nigeria. The famous Jonas Mine in Brazil has
alos produced similar colors.
