Tom found one of the biggest diamonds(鉆石) in the world right in his own back yard(后院). He sold the stone to a diamond dealer(鉆石交易商) for over three hundred thousand dollars. In New York, the diamond was resold--this time for almost eight hundred thousand dollars. This true value of diamond is never known until it has been cut. Once cut successfully, its value can increase a thousand times. It’s easy to understand why the owner of the biggest diamond went to the best diamond cutter he knew. In order to make best use of it, Kaplan, the cutter, studied the diamond for twelve whole months.

When Kaplan felt he was ready to start work, he discovered a flaw(瑕疵). He had to begin his calculations all over again, otherwise he might have made the stone useless. Six more months passed, and Kaplan finally said to the owner, “I'm ready to start. It will be comparable to any other diamond in the world, plus(以及) eleven small diamonds of first-class quality.” Kaplan waited a few more days until he felt he was in the best physical and mental condition(最佳身心狀態(tài)) possible. He picked up his tools and held his breath as he made the first blow. The diamond split (切開) exactly as he promised.
