A
red diamond, which is very rare, is called " Radja intan " or King of
Diamonds; bottle-green diamonds, also rare and valuable, are " Intan
Katja hitam "; pale blue or sea-water diamonds are " Intan-ajer-Lant,"
and " Intan minjak" is the name given to brown stones. " Chaping " are
flat twin crystals. Uncut diamonds are called " podi" and when cut they
are " intan." Some fine colored diamonds have been found in the Sarawak
and other rivers, but they can only be worked in dry seasons. A round,
rolled crystal, of good color, containing a dark core, is sometimes

natural state as an amulet. They call it " Buntat intan," or " Soul of
the diamond." When this is found in a digging, the digger moves on. He
regards it as a sure sign that there are no other diamonds near. He
also has faith that if he wears the Buntat intan suspended from his
neck, it will bring him good luck in his search further.

in Australia, the diamondiferous deposits lie at a considerable
elevation above the present watercourses, though they are all near the
banks of some river.

deposits of that country and those of Brazil, that diamonds existed
there, and practically staked his reputation for sound judgment in the
matter, by assuring the Czar-
