Suffice to say here that the
Hindus rarely went below 60 feet, because they could not unwater the mine,
and that the Brazilian finds his precious stones 280 feet below the
surface. Moreover the Indian is the only true diamond: the Brazilian is a
good and the Cape a bad natural imitation.] and it has been noticed that a
crystal believed to be a diamond has been found in auriferous gravel. In
these granitic, gneissose, and quartzose formations topazes, amethysts and
sapphires, garnets and rubies, will probably occur, as in the similar
rocks of the great Brazilian mining-grounds. The seed-pearl of the
Coast-oyster may be developed into a tolerable likeness of the far-famed
pear-shaped _Margarita_ of Arabian Katifah, which was bought by Tavernier
for the sum, then enormous, of 110,000_l_.
Pearl-culture is an art now known even to the wild Arab fisherman of the
far Midian shore. Lastly, the humble petroleum, precious as silver to the
miner-world, has been found in the British Protectorate about New Town.
