"But how on earth are you going to buy all the diamonds in?
You would want the capital of a Rothschild ?" "Not so much as you think, my boy, for there are not any great amount of diamonds in the market at any one time.

The yield of the South African fields regulates the price.

I have had this idea in my head for some time, and have studied the details.

Of course, I should not attempt to buy in all the diamonds that are in the market.

A small portion of them would yield profit enough to float the firm off again." "But if you have only a part of the supply in your hands, how are you to regulate the market value?
You must come down to the prices at which other holders are selling." "Ha! Ha! Very good! very good!" the old merchant said, shaking his head good-humouredly.
