ဖော်ပြချက်/အကြောင်းအရာ:
An engaging account of the historical, social and technical dimensions of gem mining and trading in Burma. "For many centuries, Burma has been one
of the most important gem centers in the
world. The Mogaung area, practically in the
path of the famous World War II Burma
Road, is the only commercial source of
jadeite that produces qualities ranging from
the finest gem emerald green to the cheapest
utilitarian quality. The gem mines in Mogok
are the only sources of fine gem rubies; Siam
rubies are generally inferior. Only in rare
cases is a fine Siam ruby found. Today, approximately
eighty-five percent of all rubies
and sapphires mined are of Burmese origin,
especially since the Kashmir mines in India
have ceased operations on any large scale.
Despite sufficient time and adequate facilities
for making a complete and thorough
investigation, a superficial survey in the
course of several trips during the past two
years revealed the presence of immense
wealth still hidden within Burma. Until a
complete scientific investigation is made of
the gem areas in Burma, it is hoped that this
article will fill the interim gap..."
